How Investors May Respond To Power Integrations Stock (POWI) Solid State Breaker Tie Up
- In October 2026, Power Integrations and Ideal Power announced a collaboration to build a solid state circuit breaker solution for 800 VDC AI data centers by pairing Power Integrations’ 1,700 V InnoMux-2 ICs with Ideal Power’s B-TRAN switches, supported by a working prototype and planned reference design.
- The project points to Power Integrations pushing deeper into AI infrastructure by supplying always-on, self-powered protection circuitry. This could increase its content per rack and extend its role beyond traditional auxiliary power conversion in future data center designs.
- We will examine how Power Integrations' investment narrative is influenced by this self powered solid state breaker push into AI data centers.
Power Integrations Investment Narrative Recap
To own Power Integrations, you need to believe its AI data center, automotive and industrial power products can grow into a larger share of the business while the older appliance exposure stays manageable. The recent solid state breaker news fits that thesis, but does not change the near term swing factor, which is execution against high growth expectations baked into a rich P/E.
The key risk still sits in any earnings or revenue miss against those ambitious forecasts, especially with a history of declining EPS and margin pressure. Tariff sensitivity and significant recent insider selling add to that. This collaboration helps the AI story, but does not remove those pressures.
The 800 V solid state circuit breaker project with Ideal Power fits directly into the existing AI data center catalyst. Power Integrations already targets auxiliary supplies for 800 V racks and has discussed a roughly US$1b serviceable data center market by 2030. A self powered breaker using 1,700 V InnoMux 2 parts suggests additional content per rack if adoption moves from prototype to higher volumes.
That opportunity sits alongside other growth vectors, including higher voltage GaN reaching into silicon carbide territory and energy storage systems that already use SCALE 2 drivers. Execution risk remains significant given a high P/E, relatively low return on equity at 3.7%, and earnings that have declined over five years. The key question is whether this type of design win pipeline offsets those concerns.
Power Integrations' current analyst narrative points to revenues of $689.9 million and earnings of $149.1 million by 2029, based on 15.4% yearly revenue growth and an earnings increase of about $124.0 million from $25.1 million today.
Uncover why Power Integrations' fair value indicates a 70% potential upside to its current price, which could narrow quickly.
Exploring Other Perspectives
One alternate view says the real risk for Power Integrations is that all this AI data center work does not meaningfully repair past earnings pressure. The most cautious analysts were penciling in about US$715.0 million of revenue and US$164.0 million of earnings by 2029, yet still landed on a lower US$65.0 price target. Those forecasts came before this solid state breaker deal, so use them as a reference point and explore how opinions could shift as the AI protection story develops.
