핵심 재무 데이터

사업 및 운영 성과

질화갈륨(GaN) 제품군이 주요 성장 동력이었다. 파워 인테그레이션스(Power Integrations)는 연간 GaN 매출이 사상 최대치를 기록할 것으로 예상되는 가운데, 일류 가전 OEM 업체의 주요 가전제품 설계 3건을 포함한 첫 탑스위치-GaN(TOPSwitch-GaN) 디자인 윈을 확보했다고 밝혔다. 이 밖에도 미국 주요 OEM의 스마트홈 제품 및 한국 주요 OEM의 TV 설계 수주 등이 포함됐다.

통신 및 컴퓨터 부문 매출은 계절적 수요와 최근 GaN 디자인 윈에 힘입어 각각 전분기 대비 20% 이상 증가했다. 산업 부문 매출은 고전력 애플리케이션, 에너지 인프라, 철도 전반의 호조로 전분기 대비 6%, 연초 대비 13% 증가했다.

회사는 현재 고전력 게이트 드라이버 사업에서 공급 능력을 초과하는 수요를 겪고 있다. 경영진은 이러한 공급 제약의 원인으로 강력한 수요 증가뿐 아니라 패키징 및 인쇄회로기판(PCB)의 공급 제한을 꼽았다.

가전·소비재 부문 매출은 주로 에어컨 판매의 계절적 감소로 인해 전분기 대비 7% 감소했다. 특히 미국과 중국에서 주택 시장 침체와 관세 및 원자재 가격 상승에 따른 소매가 인상으로 가전제품 수요 부진이 이어졌다.

데이터센터 및 에너지 인프라

파워 인테그레이션스는 3분기에 5건의 신규 보조 전원 디자인 윈을 달성했으며, 2027년 양산에 들어갈 예정인 4건의 800V 소켓 디자인 인(설계 채택)을 확보했다고 발표했다. 데이터센터 관련 사업 기회 파이프라인은 2026년 초 대비 3배 이상 확대됐다.

경영진은 메인 전력 경로 애플리케이션용 1,250V GaN 기술에 대한 고객사의 관심이 여전히 높다고 밝혔다. 해당 애플리케이션을 겨냥한 제품은 2027년 샘플 공급을 시작해 2028~2029년에 본격 출시될 예정이다. 또한 회사는 2027년에 1,700V 기술 관련 매출 기회가 발생할 것으로 기대하고 있다.

파워 인테그레이션스는 아이디얼 파워(Ideal Power)와 고체 전자식 차단기(solid-state circuit-breaker) 솔루션을 공동 개발하고 있다. 제안된 아키텍처는 회사의 1,700V 이노먹스(InnoMux) 기술을 활용해 800V 버스에서 제어 전자 장치에 전력을 공급한다. 경영진은 이 프로젝트가 현재 레퍼런스 플랫폼을 개발 중인 초기 단계라고 설명했다.

에너지 인프라 부문에서는 미국의 주요 공급업체로 알려진 신규 고객사로부터 고부가가치 배터리 저장 장치 설계를 수주했다. 아울러 기존 고전력 고객사 한 곳도 미국의 일류 하이퍼스케일러에 배터리 저장용 인버터를 공급하고 있으며, 2027년에 복수의 신규 고객사를 대상으로 양산을 확대할 계획이다.

자동차 부문

파워 인테그레이션스는 3분기에 독일 유수 완성차 업체의 인버터 비상 전원 공급 장치를 포함해 10건의 자동차 분야 디자인 윈을 확보했다. 이에 따라 자동차 관련 파이프라인은 연초 대비 40% 이상 증가했다.

경영진은 분산 전원 아키텍처, 배터리 전압 상승, 12V 배터리의 제거 가능성 등으로 인해 차량당 고전압 소켓 수가 증가할 것으로 예상하고 있다. 회사는 이러한 추세에 힘입어 향후 4~5년 동안 차량당 공급 가능한 반도체 탑재 금액이 한 자릿수 달러에서 100달러에 육박하는 수준까지 늘어날 수 있다고 추산했다.

경영진 가이던스

매출 가이던스 중간값인 1억 2,200만 달러 기준, 경영진은 4분기 매출이 전년 동기 대비 18% 증가하고 2026년 연간 매출은 7% 성장할 것으로 예상하고 있다.

이번 전망치는 산업 부문의 지속적인 호조와 최근 디자인 윈의 기여를 전제하면서도, 가전·소비재 수요 둔화, 높은 유통 채널 재고, 패키징 및 인쇄회로기판(PCB) 등 일부 분야의 공급 제약으로 상쇄될 것을 반영했다. 경영진은 또한 연간 Non-GAAP 영업비용이 약 4% 감소할 것으로 예상했다.

파워 인테그레이션스는 데이터센터, 에너지 인프라, 자동차 부문 확장에 힘입어 2031년까지 유효시장(SAM)을 2배로 확대하는 것을 목표로 하고 있다. 회사는 2027년 3월 8일 인베스터 데이(Investor Day)에서 전략과 목표 비즈니스 모델에 대한 세부 내용을 공개할 계획이다.

리스크 및 점검 요인

• 유통 채널 재고는 회사의 목표치인 8주를 크게 상회하는 11.8주로 증가했다. 경영진은 고객사들이 추가 완충 재고를 유지하는 동안 채널 재고가 높은 수준을 지속할 것으로 예상하고 있다.
• 가전제품 재고 개선에는 1~2개 분기가 걸릴 수 있으며, 지연된 스마트미터링 프로젝트가 유통 채널에서 소진되는 데는 2~3개 분기가 소요될 수 있다.
• 경영진은 완충 재고 요건이 완화될 때까지 2027년에도 유통 채널 재고가 9~10주 수준에 머물 수 있다고 밝혔다.
• 패키징 및 인쇄회로기판(PCB) 공급 제약으로 인해 현재의 고전력 수요를 모두 충족하는 데 한계가 따르고 있다.
• 주택 시장 침체와 가전제품 가격 상승으로 인해 가전·소비재 수요는 여전히 부진한 상태다.
• 메모리 부족 현상이 개인용 전자기기 및 컴퓨팅 부문에 영향을 미치고 있으나, 경영진은 고객사 믹스와 신규 디자인 윈 덕분에 파워 인테그레이션스에 미치는 영향은 완화되고 있다고 언급했다.
• 회사의 1,250V GaN 기술은 차별화되어 있으나, 경영진은 고객사의 부품 조달 요건으로 인해 도입 과정에서 어려움이 발생할 수 있음을 인정했다.

애널리스트 Q&A 주요 내용

경영진은 OCP 서밋(OCP Summit)에서의 논의를 통해 800V 기술의 기회에 대한 시각이 랙 수준의 전력 변환을 넘어 에너지 인프라, 배터리 저장 장치, 고체 전자식 변압기로까지 넓어졌다고 밝혔다. 보조 전원이 가장 즉각적인 기회인 반면, 메인 전력 경로용 1,250V GaN 제품은 상용화까지 더 긴 시일이 걸릴 것으로 전망된다.

유통 채널 재고와 관련해 낸시 어바(Nancy Erba) 최고재무책임자(CFO)는 4.5주 증가 요인이 가전 부진, 미터링 프로젝트 지연, 고객사의 완충 재고 요건에 비교적 고르게 분산돼 있다고 설명했다. 이 중 완충 재고 요인은 예측 가능성이 가장 낮으며, 이로 인해 2027년 내내 재고가 정상 목표치를 웃돌 수 있다고 덧붙였다.

경영진은 고전력 부문의 공급 제약이 단순한 공급망 차질 때문만이 아니라 수요 증가를 반영한 것이라고 명확히 했다. 회사는 PCB 및 패키징 조달 속도를 높이기 위해 공급업체들과 협력하고 있다.

파워 인테그레이션스는 포트폴리오 확장을 위해 파트너십과 잠재적 인수를 검토하고 있으나, 자체 개발(organic development)이 여전히 최우선 과제라고 밝혔다. 경영진은 자동차 및 데이터센터 전력 시스템 분야의 인접 기회를 확인했으나, 잠재적 거래에 대한 세부 사항은 밝히지 않았다.

Jennifer Lloyd

Thank you, Joe, and thanks, everyone, for joining us. We delivered solid Q3 results with revenue up 5% sequentially, led by strong growth from GaN products. We beat our outlook on gross margin and expenses, reflecting our continued emphasis on profitability. Our non-GAAP operating margin was up more than 6 points year-over-year in Q3, while non-GAAP EPS rose by 28%. These results demonstrate that we are executing well across our end markets. Industrial demand remains healthy with particular strength in energy infrastructure and rail. In fact, we currently have more demand than we can satisfy in our gate driver business due to certain supply constraints.

In personal electronics and computing, we saw strong sequential growth in Q3, driven by new GaN design wins and seasonal ramps. While memory shortages are a factor in these markets, the impact on our business is mitigated by our customer mix and new design wins. In the consumer market, which makes up 1/3 of our sales, demand continues to be soft due largely to stagnant housing markets and higher prices for appliances driven by tariffs and rising raw material costs. Against this uneven backdrop, we are on track to achieve our key financial and operational priorities for '26. These include revenue growth, improved profitability in the markets we serve today, advancement of our GaN technology road map and progress in our strategic pivot to the data center, EV and energy markets to drive faster growth in the years ahead.

I'm excited about our progress in each of these areas, and I'll provide an update on each, starting with our core business, where growth is being led by penetration of GaN across our end markets. We are on track for a record year of GaN revenue and had another strong quarter of design wins as customers look to our GaN products to improve efficiency and reliability. That includes our first design wins with TOPSwitch-GaN, which we introduced earlier this year, winning 3 major appliance designs at top-tier OEMs. Other wins include a recently announced smart home product for a major U.S. OEM and a TV design for a major Korean OEM using a GaN chipset addressing both AC to DC conversion and power factor correction. Now I'll turn to data center, where our high-voltage GaN continues to open doors at customers designing 800-volt systems.

At last month's OCP Summit, we met with hyperscalers, XPU suppliers, power supply and server ODMs and suppliers of energy infrastructure. Our discussions reinforced the demand for technologies that maximize power density and efficiency in 800-volt data centers. Engagements span applications from grid to rack, ranging from solid-state transformers and renewable energy to high-power sockets in the rack and power side car as well as a diverse range of AUX power sockets throughout the data center. For high-power sockets, customers continue to show strong interest in our 1,250-volt GaN to optimize power density, both by collapsing stacked power stages to reduce board area and by taking advantage of GaN high switching frequency to shrink magnetic components.

We are developing a range of high-voltage GaN products for the main power path, reflecting customer interest in a variety of integration levels and package configurations. These products are expected to sample to customers in '27 and then roll out in the '28, '29 time frame. Auxiliary power represents our most immediate opportunity to penetrate 800-volt architectures. We are seeing strong growth this year in AUX power for existing server architectures, including 5 new design wins in Q3, and we have 4 design-ins for 800-volt sockets scheduled to begin production in '27. Our opportunity pipeline has more than tripled since the start of the year and now includes a wide variety of 800-volt designs, including AUX supplies for compute trades, IT racks and side cars as well as network switches, fan power modules and solid-state circuit breakers.

In conjunction with the OCP Summit, we announced a collaboration with Ideal Power on a solution for solid-state circuit breakers. The collaboration addresses the need for innovative approaches to circuit protection in high-power, high-voltage data center environments, where mechanical circuit breakers are too slow to protect the valuable rack equipment. Existing electronic breakers introduce losses into the system, both from the protection device itself and the surrounding control electronics. So as rack power levels rise to hundreds of kilowatts and higher, any drain on system efficiency is a significant problem. An added challenge is that electronic breakers must be powered and in 800-volt systems, the power source is usually the 800-volt bus itself. That means the AUX supply must be capable of handling an 800-volt input.

So in the architecture we're developing with Ideal Power, our 1,700-volt InnoMux handles the 800 volts with ample margin. We power the intelligence that controls the ideal protection switch, which in turn protects the power path to the compute load. The result is an efficient self-powered breaker that meets the needs of 800-volt data centers, and we're excited to partner with Ideal Power on this innovative solution. Customer engagements for data center involve not just rack-level power conversion and protection, but also solutions for beyond the walls of the data center. Attach rates of battery storage systems to data centers are projected to rise rapidly in the years ahead, and we are well positioned to capitalize with our successful high-power gate drivers.

One of our top high-power customers is now supplying battery storage inverters to a top U.S. hyperscaler with plans to ramp with multiple new customers in '27. We added to our position in battery storage in Q3 with a high-value design win at a new customer, a major U.S. supplier of energy infrastructure. We are also expanding our customer engagements on solid-state transformers being developed for later phases of the 800-volt transition. Our high-power gate drivers are an attractive solution for driving switching modules and silicon-carbide-based SSTs, while GaN-based SSTs are an emerging application for our high-voltage GaN technology.

Finally, turning to automotive. We won 10 new designs in Q3, including an inverter emergency power supply for a top German automaker, and our pipeline has increased by more than 40% since the start of the year. We believe the outlook for the EV market is promising as higher gas prices have renewed consumer interest and the pricing delta between EVs and ICE vehicles continues to shrink. OEMs are moving to distributed power architectures in which micro DC to DC converters will power subsystems from the main battery instead of the lead acid batteries. One of our Chinese automotive customers recently announced its intention to eliminate the 12-volt battery, and we expect other OEMs to follow suit.

Meanwhile, rising battery voltages are driving interest in our higher voltage GaN, not only for low-power sockets, but also higher power DC to DC converters and onboard charging. Together, these 2 architectural trends have the potential to dramatically increase the number of high-voltage sockets per vehicle, driving our available dollar content from single-digit dollars to nearly $100 over the next 4 to 5 years and significantly expanding our SAM. In closing, we're excited about the opportunities ahead of us in data center, energy infrastructure and automotive. We expect these markets to drive rapid growth in our SAM with a goal to double SAM by 2031. Our strategy for driving revenue growth in these markets is taking shape, and I'm confident in our team's ability to execute the strategy.

I'm delighted to announce a new addition to the team, Tony Stratakos, who will join us next week as our Chief Technology Officer and SVP of Engineering. Tony is a noted thought leader in power semiconductors, having founded Volterra, served as CTO at Maxim Integrated and later founded a company specializing in utility-scale battery storage systems. I'm pleased to have Tony joining the team, and I look forward to introducing our executive team and providing an in-depth discussion of our strategy at an Investor Day in March 27. Now I'll turn it over to Nancy for a review of the financial highlights.

Nancy Erba

Thanks, Jen, and good afternoon. Our Q3 results demonstrate continued progress on revenue growth, margin expansion and cash generation. We reduced balance sheet inventory for the third consecutive quarter and announced an increase in our quarterly dividend. These results reflected disciplined execution across the company. Channel inventory increased during the quarter, reflecting both softer demand in certain markets and higher customer buffer stock requirements, which I'll discuss in more detail. Revenue for Q3 was $125.5 million, up 6% from a year ago and 5% sequentially.

The communications and computer categories each grew more than 20% sequentially on a combination of seasonal strength and recent GaN design wins. The industrial category continues to show healthy growth with a 6% sequential increase in Q3 and 13% growth year-to-date compared to last year. That strength led by high power has been fairly broad-based within the industrial category. Consumer revenue was down 7% from the prior quarter, driven mainly by seasonally lower revenue from air conditioning. As Jen noted, we have seen continued softness in appliances as that market continues to feel the effects of higher retail prices and weak housing markets, especially in the U.S. and China.

As previewed in my introduction, channel inventory rose by 4.5 weeks during the quarter to 11.8 weeks. Three factors drove this increase. The first is softness in appliances, where we expect sell-through to take 1 to 2 quarters to improve. The second is project delays in metering, particularly in India. We are starting to see signs of improving sell-through in metering in Q4 already and expect project launches to continue ramping through 2027. The third is channel partners building inventory to support end customers' higher buffer stock requirements. Some replenishment was expected as we entered Q3 with below normal channel inventory of 7.3 weeks, but the increase was higher than anticipated.

Both our channel partners and end customers tell us that amid broader supply chain constraints, they are holding additional buffer stock. Channel inventory, therefore, is likely to remain above our 8-week target while these conditions persist. We will continue to monitor sell-through and customer requirements closely as we manage shipments. Turning to gross margin. Non-GAAP gross margin was 55.2% for the quarter, above the high end of our outlook and up slightly from the prior quarter, benefiting from improved mix and higher manufacturing volumes. Non-GAAP operating expenses in Q3 were $42.4 million, down $2.8 million from the prior quarter.

Compared to the third quarter of last year, non-GAAP operating expenses were down more than 10%. We remain focused on disciplined expense management while protecting priority investments in GaN and our strategic growth markets. Our objective is to maintain ongoing profitability improvements while advancing the technology and customer programs that support longer-term growth. Non-GAAP operating margin for Q3 was 21.4%, up more than 4 points from the prior quarter and more than 7 points higher than the full year 2025 figure. This improvement reflects the operating leverage in our business model that comes with revenue growth and disciplined expense management.

Non-GAAP earnings for the quarter were $0.46 per diluted share, up 24% sequentially and 28% from a year ago. Turning to the balance sheet and cash flow. Cash flow from operations was $43 million for the quarter, while CapEx was $6 million, resulting in free cash flow of $37 million. Lower inventory was a significant contributor, falling by more than $7 million during the quarter. Days on hand fell by 19 days to 246 days at quarter end. Cash and investments on the balance sheet increased by $25 million during the quarter to $288 million. Reflecting the strength of our balance sheet and confidence in our ability to grow cash flow going forward, our Board of Directors has raised our quarterly dividend to $0.22 per share beginning in Q1 '27.

I'll now review the fourth quarter outlook. We expect revenue to be between $118 million and $126 million. At the midpoint, that would be an increase of 18% from the fourth quarter of last year and bring our full year growth rate to 7%. Our outlook reflects continued industrial strength and contributions from recent design wins balanced against softer consumer demand, elevated channel inventory and supply constraints, including packaging and PCBs. I expect non-GAAP gross margin for Q4 to be in the range of 55%, plus or minus 0.5 point. Non-GAAP operating expenses for Q4 should be in the range of $43 million, plus or minus $0.5 million. At the midpoint, that would be a slight increase from Q3, but once again lower than a year ago.

We are on track for a full year reduction of about 4% as we continue to drive expense discipline while protecting priority investments in our strategic growth markets and advancing our technology road map. Finally, I expect non-GAAP operating margin for Q4 to be between 19% and 21%. In summary, Q3 showed our ability to improve profitability and generate strong cash flow. We maintain measured in our near-term expectations for market growth while encouraged by our design win momentum and longer-term opportunities. Our focus is on disciplined execution, investing selectively in our strategic priorities and translating growth into sustainable earnings and cash flow to drive shareholder value.

We look forward to sharing more about our strategy and target business model at our upcoming Investor Day on March 8, 2027, in New York. Joe will be sharing more details in the coming weeks. And now Ben, let's begin the Q&A session.

Operator

[Operator Instructions] Your first question from the line of David Williams of Needham & Co.

질의응답

David Williams

Maybe first, Jen, you had talked about at OCP, there were -- it seemed like a lot of enthusiasm around the higher voltage power architectures. Was there anything there that changed maybe your view? It sounds like you're getting the design wins, better opportunities. But do you think there's anything there that pulls things forward or makes you maybe a little more optimistic about that 800-volt opportunity?

Jennifer Lloyd

Yes. Thank you, David, for the question. Yes, I mean, what we've talked about before, and we continue to be really happy about and our progress on, we continue -- first of all, we're engaging across the ecosystem. We are seeing the OCP designs growing in terms of our pipeline and our revenue across a broad range of power. And we -- as I mentioned in the prepared remarks, we are now seeing design-ins specifically for 800 volts there. So we're happy about that, and we're continuing to demonstrate good performance in available sockets.

As we've also talked about, the main path architecture for us, we're really focused on that opportunity with our 1250-volt GaN. So a little bit further out in time from the current 650-volt designs that are going on. I think what was exciting at OCP is really seeing the expansion of the partnerships beyond what's inside the data center to some of the new things that we're seeing on the racks as well as what's happening outside the data center. And so as we discussed, we're pretty excited about our high-power business, its ability to address some of those opportunities. So yes, I think we're seeing a broader opportunity for ourselves.

David Williams

Great. And maybe just on the inventory dynamics. It seems -- I think it's more of your exposure there maybe on the consumer side, but that's kind of a different story than what we've heard from a lot of your peers. Is there any other dynamics that we should be thinking about there? I mean, obviously, you pointed to multiple things that drove that. But do you still feel like the demand is there and there's no real softening on the broader demand environment? Does it feel like that is the case? Or is there other things maybe that we should be thinking about driving that inventory?

Nancy Erba

If I talk about consumer first, we are seeing softness there, and it is typically a softer quarter with air conditioning, as you're well aware in terms of that cyclicality. So that inventory buildup in China, and we are looking at it really region by region and by channel partner, as I talked about in the past, that buildup will take a couple of quarters to work through. If I look at India and the metering specifically, that is really a delay in project starts within India, which have now started to loosen up. And we've already started to see that in Q4. So I feel very good about that that higher inventory in India moving through starting in Q4, but really into next year as those larger projects kick off and get that moving within the channel.

And then the third area is one on the supply side, which is actually new. We -- as you can imagine, we've been having very frequent discussions with channel partners and our end customers as we saw this build up. And certain customers -- end customers are requiring these channel partners to hold additional inventory as they are seeing other supply constraints. And so that piece is the piece that will likely take a little bit longer to work through, and it's really going to depend on when those end customers allow that buffer stock level to decrease. But that demand is continuing to be healthy. And as Jen said, we're seeing more and more wins that are going to drive continued revenue growth. And unfortunately, it turned into a blip this quarter in terms of that higher level of weeks on hand.

David Williams

But it doesn't feel like it's potentially a golden screw type scenario where you're building inventory, waiting for other critical components in the supply chain?

Nancy Erba

I think some customers may be. But on a broader base, I think, no, we have multiple reasons for why we saw the buildup.

Operator

Your next question from the line of Tore Svanberg of Stifel.

Tore Svanberg

Maybe following up on that last topic. So I'm just trying to understand, Nancy. So is it fair to say that the 4.5 weeks is sort of equally distributed within those 3 reasons? And assuming that supply will remain tight for the industry, as you sort of go through '27, would you expect the channel inventory to be a little bit more elevated than normal? Would you target be kind of more like 9 weeks versus 8? So any color there?

Nancy Erba

I think it's fairly distributed. China with appliances, we saw that tick up later in the quarter. So it seemed to be moving fairly well in the first part of the quarter and then picked up towards the end. That I would expect to move through in the next couple of quarters, as I said. I think the metering will move through in the next call it, 2 to 3 quarters as well as those projects get underway. The one that is a little bit more challenging to predict is those that are increasing buffer stock. So I think for Q4, the level of weeks on hand will remain higher than we have targeted.

I think for next year, it is potentially a scenario where it sits at 9 to 10 weeks until we see the reduction in buffer stock. But we'll have to just keep watching it and stay in connection with our end customers, not only our channel partners, but their customers to really understand what -- when they start to see that buffer stock requirement reduce.

Tore Svanberg

Got it. But it's fair to say that it's probably not going to go above 11.8 weeks or at least you wouldn't let it go above that level at this point?

Nancy Erba

We certainly will do everything we can not to have that happen, yes.

Tore Svanberg

Very good. And as a follow-up for you, Jen, I do recognize 1,250, your GaN technology is a little further out. You didn't -- you also didn't mention 1,700 volt on the call. Just curious, especially given OCP and so on and so forth, like what's the level of interest in both of these very unique GaN technologies that you're now sampling?

Jennifer Lloyd

Yes. So I thought I did mention 1,700 volt. Maybe I didn't, but a couple of the wins that we referenced were using the 1,700-volt technology, just to clarify that. I think the level of interest is high. I mean what I'm really hearing again, and it's back to just the criticality of power in these systems is that the interest is high in technologies that will improve the efficiency, the power density, the board area, which translates to power density. The challenge with the uniqueness is the goals around sourcing, right? So right now, our 1,250 is very unique. And so we're working with our customers on it, but we will have to align and meet some of the challenges that they'll see with that as a unique technology.

Tore Svanberg

Very good. So it's fair to say that the design wins for both 1250 and 1700volt as far as materializing the revenue, we're looking at 2028, 2029 time frame.

Jennifer Lloyd

No, no, 27 for the 1,700. The 1,700 will be in '27 and it's it right? And then plane will be out in '28, '29.

Your next question from the line of Christopher Rolland of Susquehanna.

Christopher Rolland

I guess mine is around your supply chain, your foundry partners. They're a little bit different from others. Some I can consider a little bit more unconventional. And this has benefited you in the past when others have been kind of super tight, expanding lead times, et cetera. I guess, first of all, have you seen this as an opportunity? Is this something that you talk with your partners about maybe more availability of supply or lower lead times? And secondly, do you think this has anything to do with the channel build, maybe the channel getting these parts because they are available in front of either expanding lead times or price hikes like they've seen from other partners?

Nancy Erba

I think that is a potential. I want to see Q4 and Q1 start to improve and see things move through. But that availability certainly has benefited us historically. As Jen mentioned, in certain areas, in particular, in high power, we're actually tight ourselves and are asking customers to provide longer visibility to their forecast because we're seeing some level of shortages in PCBs as well as in packaging needs. And so we're starting to experience a little bit of that as well on the high-power side. On low power, certainly, the availability is a benefit to us to be able to meet customers' needs, and we are working closely with our end customers to make sure that they understand and that we can see that visibility to make sure that, that continues to be an advantage for us.

Christopher Rolland

Excellent. I think you preempted my second question. You may have been referring to the silicon gate drivers. You said they were supply constrained. I guess you might have just mentioned those choke holds, but if there's anything else to discuss there? And then also just the demand that you're seeing for this, is it substantially above? Or is it really just the supply chain factors?

Nancy Erba

We are -- we have right now more demand in our high-power business than we can supply, which is good, right? It's building that backlog. And we are doing everything we can and working with our supply chain to expedite and bring in the -- and I'll use PCBs as an example to try and bring in more in advance so that we can meet that demand.

Christopher Rolland

Is that from an upside in demand or your demand expectation? Or is it just -- are you highlighting the supply chain issues?

Nancy Erba

No, it's an increase in the demand, which is great. And as Jen mentioned, that's one of the areas that we are hearing a lot of interest from our customers and from new customers in terms of our capabilities in high power is certainly a large area of focus in the industry right now.

[Operator Instructions] Your next question comes from the line of David Williams of Needham & Co.

David Williams

So Jen, I just want to ask, I know in the past, you've talked about your portfolio being a bit more narrow and you would like to expand that a bit. And of course, you have those initiatives internally to build that organically. But if you look out and think about inorganic opportunities, how do you rate the environment today? Are there opportunities for you? And when could we see potentially you being more acquisitive in the future if that is where you'd like to go?

Nancy Erba

Well, we're probably not going to preannounce anything here on the call. That's a joke. But we are, as we have mentioned, actively evaluating different technologies and are looking at the ecosystem around us and whether that's through partnerships or potential M&A are looking to expand our product portfolio. Our first priority is to do that organically, and I think Jen will talk a bit about that with Tony joining. But we are absolutely looking at other ways that we can potentially use an inorganic opportunity to drive scale.

Jennifer Lloyd

Yes. And I'll just add to that, David. We are looking at what we can do organically. And I think you'll hear more as time goes on. We've talked about in automotive, expanding our BOM content and some of that will be through some new topologies. And same thing in data center, we're seeing some things adjacent to our traditional space. So stay tuned on that. Yes. Thanks for asking that.

David Williams

And just maybe lastly, if I could, on the Ideal Power partnership or relationship there, can you talk to us a little bit about how that is set up? And will that be a combined technology, combined packaging? Or is it a transfer of IP? Just any color around what that relationship could look like?

Jennifer Lloyd

Sure. Yes, that's really a co-development, I would say. And what's exciting about it is that we are seeing that the 2 companies coming together, our technologies play really well together like there are advantages in combining those technologies. But it's really early days. We're co-developing. We're working on some reference platforms and demonstrating the technology to customers. We're talking to a lot of customers. But it's very early days, but we're excited about that work.

Operator

There are no further questions at this time. I will now hand the call back to Jim Lloyd for closing remarks.
