This reference design is a high efficiency, high power density and light weight resonant converter reference design. It converts a 390V input to a 48V/1kW output. The PMP20637 power stage has over 140W/in^3 power density. The whole board weight is less than 210g. With fixed 950kHz switching frequency in steady state, 97.6% peak efficiency is achieved.
