What happened

Power Integrations (NASDAQ: POWI) and Ideal Power Inc. (NASDAQ: IPWR) announced a collaboration to deliver a solid-state circuit breaker (SSCB) aimed at 800 VDC AI data center racks.S1

The joint architecture pairs Power Integrations' 1700 V InnoMux-2 power conversion ICs with Ideal Power's B-TRAN bidirectional semiconductor power switches, and the two companies have demonstrated a working prototype while working on a reference design.S1

The InnoMux-2 IC is intended to convert 800 V into isolated power for gate-drive, control electronics, sensing, and auxiliary circuitry on the breaker itself, so the SSCB can be self-powered directly from the 800 V bus without an external auxiliary supply. The IC uses 1700 V PowiGaN technology and provides multiple independently regulated outputs in place of one isolated PSU followed by multiple DC-DC converters. The B-TRAN switch then uses that local intelligence to interrupt the 800 V power path to the AI compute load.S1

The companies frame the move as a response to protection limits at higher rack power: mechanical breakers are described as too slow to protect sensitive rack equipment, while prior electronic breakers are described as adding losses that hurt system efficiency, and they must also be powered from the 800 V bus. Chris Jacobs, senior vice president of marketing and product strategy at Power Integrations, and David Somo, CEO of Ideal Power, are quoted in the release supporting that framing.S1

XAIPART take

Technical impact

XAIPART analysis The 1700 V InnoMux-2 gives meaningful headroom over an 800 V bus, which matters because wide-bandgap designs derate for surge, ringing, and de-saturated turn-off energy in SSCBs. Deriving the gate-drive, sensing, and auxiliary rails directly from the 800 V bus removes a redundant isolated PSU from the bill of materials, but it also concentrates the breaker on the highest-voltage node in the rack, so creepage, clearance, and arc-fault behavior need to be re-qualified rather than assumed in from lower-voltage breaker platforms. The B-TRAN bidirectional switch is the differentiator on the power path: a symmetrical device can interrupt fault current in either direction without the diode-bridge losses of conventional SSCB topologies, and the release explicitly contrasts this against the high conduction loss that has historically disqualified semiconductor breakers.

Market impact

XAIPART analysis For procurement, the headline risk is that mechanical 800 V breakers mature faster than semiconductor alternatives, but the upside is removing one full isolated PSU per protected 800 V feed, which compounds at hyperscaler scale. Both companies are publicly traded (POWI, IPWR), so lead times and pricing for InnoMux-2 and B-TRAN are likely to follow hyperscaler ramp announcements from NVIDIA, AMD, and the 800 V rack reference design consortia; XAIPART does not yet have a lead-time comparison, and the source did not disclose volume pricing.

Action

XAIPART analysis Design-in engineers targeting 800 VDC AI racks should request the upcoming reference design directly from Power Integrations and Ideal Power to validate the self-powered architecture against their own fault-interrupt time and isolation budgets, since the source did not disclose interruption time, peak fault current rating, or UL/IEC 489B / 60947-2 qualification status. Buyers should track both POWI and IPWR for distributor stock on InnoMux-2 1700 V variants and B-TRAN modules as the reference design approaches release, and they should not yet commit to a sole-source roadmap for the switch device given Ideal Power's still-narrow commercial footprint. A safety delta to flag internally: the breaker must be evaluated for failure-mode behavior when the 800 V bus itself collapses, because the self-powered architecture described depends on that bus being live for its own control electronics.

XAIPART Forecast

XAIPART analysis XAIPART expects that, if a published reference design from Power Integrations and Ideal Power is not demonstrated publicly interrupting an 800 VDC fault within 9 months from the 2026-10-12 announcement (i.e., by 2027-07-12), this collaboration is unlikely to set the de facto topology for 800 VDC SSCB in AI racks and incumbent mechanical or SiC-based breakers will retain design wins; conversely, if a reference design with a published fault-interruption time under 100 microseconds and a published 800 V efficiency figure above 99 percent lands by 2027-07-12, the InnoMux-2 plus B-TRAN pairing is XAIPART's expected reference topology for self-powered 800 VDC solid-state breakers through 2028.

Facts are as reported by the cited source. The design-in, sourcing and forward-looking statements above are XAIPART's analysis, not the source's claims. Uncertainty: fault-interruption time, peak fault current rating, efficiency percentage, qualification status, pricing, and lead time were not disclosed by the source; the collaboration is single-sourced from a joint press release and has not been independently verified.

Corrections: none at publication. This brief will be updated with a timestamp if the source corrects its report.
