Navitas Semiconductor and Microchip Technology have announced a new reference design platform for AI data centers that integrates digital power control with gallium nitride technology. This collaborative solution is engineered to support the Open Compute Project 800V DC standard to enhance efficiency in server rack power architectures.
Why it matters
This partnership aims to help developers reduce design risks and accelerate the deployment of critical AI infrastructure. By moving toward 800V DC rack power architectures, the industry seeks to significantly improve overall power density and operational efficiency.
The reference design achieves a power density of 2,100 W/in³ and 96% peak efficiency at a 1 MHz switching frequency. It utilizes 16 NV6034 GaNFast FETs paired with a dsPIC33AK controller featuring a 200 MHz 32-bit core.
The players
Navitas Semiconductor
Based in Torrance, California, this company specializes in gallium nitride power integrated circuits for energy-efficient electronics.
Microchip Technology
Headquartered in Chandler, Arizona, this firm is a leading provider of smart, connected, and secure embedded control solutions.
The details
The platform combines 800V DC-to-50V DC and 50V DC-to-6V DC conversion stages into a single converter using a stacked half-bridge topology. It also incorporates hardware-based security via the TA100 CryptoAuthentication device to provide a trusted foundation for authentication.
Timeline
October 05, 2026: Navitas and Microchip announced the new reference design.
October 12-15, 2026: The solution will be showcased at the OCP Event.
Roadmap
The transition to 800V DC rack power architectures represents a fundamental shift in how the data center industry manages the massive power demands of artificial intelligence. This collaboration positions these firms to capture a larger share of the infrastructure market as legacy voltage systems are phased out in favor of higher density alternatives.
For data center operators and hardware engineers, this reference design provides a ready-to-use pathway to implement more efficient power systems. This shift could lead to more compact AI server designs, potentially lowering the physical space requirements and electricity usage for large-scale computing facilities.
The takeaway
The move toward 800V power architectures highlights the critical importance of power efficiency in the scaling of modern AI capabilities. Engineers looking to adopt these technologies should prioritize evaluating the trade-offs between switching frequency and thermal management in their own designs.
What happens next
The reference design will be officially showcased at the OCP Event in San Jose, California, from October 12-15, 2026.
