Power Integrations and Ideal Power to collaborate on SSCBs. Wednesday 14th October 2026 Partnership addresses protection, control, and power conversion challenges in 800 VDC AI data centres Power Integrations and Ideal Power, developer of the B-TRAN bidirectional power switch, are working together to deliver a solid-state circuit breaker (SSCB) solution providing fast, efficient, always-on protection that scales with the 800 VDC transition in AI data centres. The companies will collaborate on a new architecture combining Power Integrations' 1700 V InnoMux-2 power conversion ICs with Ideal Power's B-TRAN switches to deliver a self-powered, intelligent, ultra-fast SSCB. They have also demonstrated a working prototype and are working on a reference design. In the next generation intelligent SSCB architecture, the InnoMux-2 IC converts 800 V into isolated power for gate-drive, control electronics, sensing, and auxiliary circuitry. Ideal Power's B-TRAN switch uses that intelligence to protect the 800 V power path to the AI computing load. The InnoMux-2 IC features 1700 V PowiGaN technology, which can operate from an 800 VDC bus with significant margin. The IC provides multiple independently regulated outputs instead of a conventional architecture with one isolated PSU followed by multiple DC-DC converters. This self-powered protection solution eliminates the need for an external auxiliary supply while enabling ultra-fast fault isolation. according to the company. "High efficiency, ultra-fast fault interruption is essential for enabling the migration to 800 VDC AI data centres and energy infrastructure. Traditional protection methods are proving to be inadequate. Mechanical breakers are too slow, while previous semiconductor-based breakers have historically been disqualified by high power loss," said David Somo, CEO of Ideal Power. "Power Integrations offers a unique combination of 1700 V GaN capability, multiple independently regulated outputs, high integration, and a compact solution footprint that is well suited to our 800 VDC solid-state circuit breaker architecture, which must meet demanding power efficiency requirements and strict mechanical constraints." SPONSOR MESSAGE Unifying software and semiconductor development. Software-defined workflows are reshaping the way smart, connected products are designed. The merging of software functionality and hardware intricacies is pushing traditional workflows beyond their capabilities, leaving teams at a developmental crossroads. With this fundamental shift comes the critical need for end-to-end traceability and robust collaboration tools that easily integrate into existing workflows to unify hardware and software development. In this new software-defined era, how can companies break down the silos that have historically defined software and silicon development workflows?

Power Integrations and Ideal Power collaborate on efficient, always-on solid state circuit breakers for 800 VDC AI data centers. 2 minutes read Power Integrations, the leader in high-voltage integrated circuits for energy-efficient power conversion, and Ideal Power Inc., developer and provider of its innovative and widely patented B-TRAN(R) bidirectional semiconductor power switch, announced a collaboration to deliver a solid-state circuit breaker (SSCB) solution providing fast, efficient, always-on protection that scales with the 800 VDC transition in AI data centers. The companies will collaborate on a new architecture combining Power Integrations' 1700 V InnoMux-2 power conversion ICs with Ideal Power's B-TRAN(R) switches to deliver a self-powered, intelligent, ultra-fast SSCB. They have also demonstrated a working prototype and are working on a reference design. Rising voltages and rack power levels in AI data centers create a need for innovative approaches to circuit protection. Mechanical circuit breakers are too slow to protect sensitive rack equipment, while existing electronic breakers introduce losses, reducing system efficiency. Further, electronic breakers must be powered from the 800 V bus. In the next generation intelligent SSCB architecture, the InnoMux-2 IC converts 800 V into isolated power for gate-drive, control electronics, sensing, and auxiliary circuitry. Ideal Power's B-TRAN(R) switch uses that intelligence to protect the 800 V power path to the AI computing load. The InnoMux-2 IC features 1700 V PowiGaN technology, which can operate from an 800 VDC bus with significant margin. The IC provides multiple independently regulated outputs instead of a conventional architecture with one isolated PSU followed by multiple DC-DC converters. The result is a highly efficient, self-powered protection solution that eliminates the need for an external auxiliary supply while enabling ultra-fast fault isolation. "As AI data centers move toward 800 VDC power architectures, the industry must address new challenges in power conversion, control, and protection at the system level," said Chris Jacobs, senior vice president of marketing and product strategy at Power Integrations. "By combining Power Integrations' 1700 V InnoMux-2 IC with Ideal Power's innovative bidirectional solid-state circuit protection, we are helping enable intelligent 800 VDC power architectures that improve efficiency, resiliency, and scalability in next-generation AI data centers."

Power Integrations jumps 5.3% amid sector-wide rally. Power Integrations surged 5.3% to close at $54.25 on Friday as semiconductor stocks rallied broadly, with the company riding a wave of strength across sector... AlphaStreet Newsdesk powered by AlphaStreet Intelligence Power Integrations surged 5.3% to close at $54.25 on Friday as semiconductor stocks rallied broadly, with the company riding a wave of strength across sector peers. The stock joined four other semiconductor names in posting strong gains, with the group showing coordinated upward momentum that lifted Power Integrations' market cap to $3.1 billion. Stocks & Bonds The rally reflected widespread buying across the semiconductor space. Diodes Incorporated climbed 6.3%, Navitas Semiconductor advanced 4.2%, and Power & Digital Infrastructure Acquisition Corp jumped 9.3%. The strongest move came from Wolfspeed, which surged 11.0%. Power Integrations' 5.3% gain positioned it in the middle of the pack among this group of sector peers, all of which saw buyers step in during Friday's session. Trading volume came in at 164,908 shares as investors participated in the sector-wide move. The coordinated gains suggest a broader shift in sentiment toward semiconductor names rather than company-specific news driving the action. When multiple stocks in a sector move together with this kind of magnitude, it often signals either rotation into the space from institutional investors or a reaction to macro factors affecting the entire group. The challenge for investors now is determining whether this rally has legs. Sector-wide moves can be powerful but fleeting, especially when they're not anchored to specific fundamental catalysts like earnings beats or product announcements. Power Integrations will need to demonstrate its own operating momentum to sustain gains beyond a broad-based sector rotation. Company Earnings What to Watch: Monitor whether semiconductor stocks can hold these gains in next week's trading, and watch for any company-specific catalysts from Power Integrations that could justify further upside independent of sector momentum. Volume trends will be key to gauging whether institutional money is genuinely rotating into the space or if this was a one-day move.
