The 800V rack transition was still an infrastructure warning in August. Microchip and Navitas have now turned one critical stage into a reference implementation instead of a block diagram. The platform converts 800V DC directly to 6V DC, collapsing the usual 800V-to-50V and 50V-to-6V stages into one converter with hardware, software, and design documentation.
The power board pairs a dsPIC33AK controller and TA100 root-of-trust device with 16 Navitas 650V GaN FETs. It targets 96% peak efficiency at full load, 1 MHz switching, and 2,100 W/in3 power density. Those numbers matter, but the development signal is the packaged validation surface: deterministic control, secure boot, authenticated updates, and a physical board that teams can measure before committing a rack architecture.
Builders evaluating OCP 800V can buy down risk with a board and a test plan instead of starting with converter topology selection. Over the next 12 months, power vendors that ship parts without runnable reference hardware will lose design-ins to vendors that ship the whole verification target.
