Power Integrations (POWI) Targets 800 VDC AI Data Center Breakers

Simply Wall St · 1d ago
  • Power Integrations (NasdaqGS:POWI) and Ideal Power announced a collaboration to develop solid-state circuit breakers for 800 VDC AI data centers.
  • The partners have shown a working prototype that combines Power Integrations’ high-voltage switch technology with Ideal Power’s power semiconductor architecture.
  • The companies plan to create a reference design aimed at improving protection and uptime in high-power artificial intelligence facilities.
  • This new Power Integrations and Ideal Power solid-state breaker project slots into a wider picture our research has uncovered. Take a look at 3 warning signs we have identified for Power Integrations.

Power Integrations is one of several businesses tied to the build out of AI power infrastructure, so it is worth weighing the broader set of related stocks exposed to this theme through 92 AI infrastructure stocks.

Power Integrations designs high-voltage analog and mixed-signal chips that sit inside power supplies. This partnership plugs its core components directly into the high-demand circuitry that helps AI data centers manage and convert electricity more efficiently and with tighter control.

2 things going right for Power Integrations that this headline doesn't cover.

How this AI breaker project speaks to the Power Integrations Narrative

The big idea behind the Power Integrations Narrative is simple. The story leans on high-voltage GaN and AI data center design wins gradually replacing lower quality appliance-driven revenue with higher margin, stickier infrastructure content, and this breaker partnership lands squarely in that zone.

"AI data center power opportunities, including auxiliary supplies for NVIDIA’s 800 V racks using 1,700 V InnoMux-2 ICs and a longer-term path into the main GPU power stage…"

See how the full story points towards a $77.50 fair value for Power Integrations.

This solid-state breaker project gives that AI data center premise tangible form. It pushes Power Integrations’ InnoMux-2 devices from the sidelines of rack auxiliaries into a protection role that touches the high-voltage bus itself, an area where peers like Infineon and Onsemi are also vying for sockets and long-lived content.

The flip side is execution risk. The Narrative already leans heavily on higher voltage GaN uptake, while analysts have flagged concentration in appliances and a history of shrinking earnings. If this collaboration stays niche or is slow to translate into multiple reference wins, the story can look stretched relative to that risk profile.

The takeaway is that the same AI breaker announcement can read as validation or overreach, depending on whether your Power Integrations view focuses more on new GaN design wins or on past pressure in the appliance-heavy parts of the business.

The Power Integrations detail most holders skip over

Hardware, chips and contracts matter, but who actually calls the shots at Power Integrations, and how their pay packets are structured, can quietly tilt the whole risk and reward profile. See who is actually steering Power Integrations, and how they are paid.
