93% Full-load efficiency (60% at 125mW): 310W industrial AC/DC reference design(PMP30521)

This reference design is a compact and high efficient two-stage power supply. The front-end stage is a CCM power factor correction (PFC) based on UCC28180.The second stage is based on UCC256304, which drives a resonant 310 W LLC converter with two outputs, 19 V and 56 V. The board does not need any auxiliary supply and draws only 250 mW from mains (with PFC off), while supplying 150 mW load.
