The 800 VDC power architecture from Texas Instruments is designed for AI data centers using the NVIDIA 800 VDC reference design, enabling two-stage conversion from 800V to GPU core power. The solution includes an 800V hot-swap controller, 800V to 6V DC/DC converter with 97.6% peak efficiency and a 6V to <1V multiphase buck converter for high-current GPU loads, supporting improved power density and simplified distribution. It targets scalable, high-efficiency power delivery for next-generation AI infrastructure and data center systems.
