Infineon Advances GaN Power for 800 VDC AI Data Centers

What happened

Infineon Technologies AG is expanding its collaboration with NVIDIA on 800 V direct-current (VDC) power architectures for AI data centers, with the latest development focusing on high-voltage intermediate bus converters (IBCs), a stage in the power delivery chain that steps down the main distribution voltage to levels suitable for downstream conversion and processor power delivery. The collaboration builds on work announced in May 2025 and further detailed in October 2025, which addressed serviceable, hot-swappable server racks operating with 800 VDC power distribution. At the IBC stage, switching frequencies up to 1 MHz enable smaller magnetic components and passive devices, reducing converter size and board height; Infineon combines its GaN portfolio with PSoC™ Control C3 controllers and EiceDRIVER™ gate-driver products to provide integrated IBC solutions, supporting conversion ratios including 800 V to 50 V, 800 V to 12 V, and 800 V to 6 V. The collaboration with NVIDIA also extends beyond intermediate bus conversion to power-path protection, including hot-swap controller functionality intended to support safe servicing and the deployment of future server boards in 800 VDC architectures.
