Navitas demos 97.5% efficient board

Navitas Semiconductor said on May 18 that it will bring new gallium nitride and silicon carbide power platforms for AI data centers to PCIM Europe 2026 in Nuremberg. The company said the lineup includes a 20-kilowatt board that converts 800 volts directly to 6 volts at 97.5% peak efficiency, and a 10-kilowatt 800-volt-to-50-volt full-brick platform rated at 98.5% efficiency. Navitas said both products are aimed at a data-center power architecture built around higher-voltage distribution and denser AI racks. ### Why is an 800V-to-6V board getting attention? Navitas said the 20-kilowatt power delivery board is designed to convert 800 volts to 6 volts in a single stage, removing the traditional 48-volt intermediate bus converter. In a March 16 release tied to NVIDIA GTC 2026, the company said that design is intended to improve system efficiency, reliability, cost and compute density. (navitassemi.com) The board’s earlier published specification sheet described a lower figure, saying the platform targeted 96.5% peak efficiency at full load with 1 MHz switching and power density of 2,100 watts per cubic inch. The May 18 PCIM release updated that headline number to 97.5% peak efficiency, suggesting Navitas is presenting a revised result or demonstration figure for the same 20-kilowatt 800V-to-6V platform. (navitassemi.com) That is an inference based on the company’s two releases. ### What is the 10kW 800V-to-50V platform for? Navitas said the 10-kilowatt platform targets the front end of rack-level conversion, stepping 800 volts down to 50 volts in a full-brick form factor. In a February release, the company said that platform delivers 98.5% efficiency and power density of 8 kilowatts per cubic inch. (navitassemi.com) Navitas said the 10-kilowatt design uses fourth-generation 650-volt GaN and its IntelliWeave digital control technology. The company said the platform is intended for next-generation AI data centers using 800-volt high-voltage direct current distribution. (navitassemi.com) ### Where do GaN and SiC fit in the same system? Navitas said its PCIM display will span the chain from medium-voltage grid conversion to on-board power delivery. The May 18 release said the company plans to show two solid-state-transformer solutions for converting medium-voltage grid power to 800-volt high-voltage DC, alongside the 10-kilowatt and 20-kilowatt data-center platforms. (navitassemi.com) The company has been framing that architecture around AI rack growth for more than a year. In a May 2025 release, Navitas said it was developing 800-volt HVDC data-center power infrastructure with NVIDIA for 1-megawatt IT racks and beyond. In a March 2024 roadmap release, Navitas said AI data centers were facing a threefold increase in power demand over 12 to 18 months. (navitassemi.com) ### Why does efficiency matter so much here? Navitas said the new platforms are meant to address both conversion losses and thermal constraints as rack power rises. In the March 16 release, the company said the 800V-to-6V board’s low profile allows close integration with the GPU board to improve transient performance and power-distribution efficiency. (navitassemi.com) The company’s own product language is promotional, but the direction is clear from the specifications it is publishing: fewer conversion stages, higher-voltage distribution and tighter board-level integration are being presented as ways to reduce wasted power and cooling burden in AI servers. That characterization is based on Navitas’s releases and datasheets. (navitassemi.com) ### When and where will Navitas show the hardware? PCIM Europe 2026 is scheduled for June 9-11 in Nuremberg, Germany, according to Navitas’s event page. Navitas said visitors can find the company in Hall 9, Booth 544, where it plans to show the AI data-center platforms along with grid and industrial electrification products.
