What happened
Power Integrations and Ideal Power have announced a partnership to develop a solid-state circuit breaker solution specifically for 800 VDC AI data center power systems. The collaboration integrates Power Integrations’ 1700 V InnoMux-2 power conversion ICs with Ideal Power’s B-TRAN bidirectional semiconductor power switch. The companies have already demonstrated a working prototype and are currently developing a reference design for the technology.
Power Integrations and Ideal Power have entered a partnership to address power protection challenges in 800 VDC AI data centers. The collaboration centers on a new architecture that utilizes Power Integrations’ 1700 V InnoMux-2 power conversion ICs alongside Ideal Power’s B-TRAN bidirectional semiconductor power switch.
The InnoMux-2 IC, which features 1700 V PowiGaN technology, is designed to convert 800 V into isolated power for control electronics, gate-drive, sensing, and auxiliary circuitry. This integration allows for multiple independently regulated outputs, which the companies claim eliminates the need for external auxiliary power supplies while facilitating fault isolation.
The companies have confirmed that they have already produced a working prototype and are currently working on a reference design to facilitate the adoption of this technology by data center infrastructure providers.

Why it matters
As AI data centers scale, they are increasingly transitioning to 800 VDC power architectures to handle higher power demands. This shift introduces significant challenges in power conversion and circuit protection. Traditional mechanical breakers are often too slow for these high-voltage environments, while existing semiconductor-based alternatives have historically suffered from high power loss. By combining Power Integrations' high-voltage ICs with Ideal Power's B-TRAN technology, the partners aim to provide a more efficient, faster-acting protection mechanism that eliminates the need for external auxiliary supplies, potentially improving the reliability and energy efficiency of AI computing infrastructure.
The transition to 800 VDC architectures is a critical development for AI data centers, which require massive amounts of power to support high-density computing loads. Standard protection methods, such as mechanical breakers, are often insufficient due to their slow response times, while previous semiconductor-based breakers have been limited by high power dissipation.
By leveraging B-TRAN technology, the partnership aims to provide a faster, more efficient alternative that can handle the high-voltage requirements of modern AI hardware. This development is significant for the broader AI industry as it seeks to optimize power delivery and reduce energy waste in large-scale data center deployments.

What to watch next
The primary focus will be the transition from the current prototype and reference design phase to commercial availability. It remains unknown when this solution will be available for purchase or what the specific pricing structure will be for data center operators. Industry observers should monitor whether this reference design is adopted by major data center hardware manufacturers and if it successfully addresses the power loss issues that have hindered previous semiconductor-based circuit breakers in high-voltage applications.
The timeline for the commercial release of the reference design remains unstated. Potential customers and industry analysts should watch for announcements regarding the integration of this technology into commercial power distribution units (PDUs) or server rack power systems.
The effectiveness of this solution in real-world, high-load AI data center environments remains to be independently verified. Future updates regarding performance benchmarks or pilot deployments by major data center operators will be key indicators of the technology's viability.
