This reference design demonstrates a half-bridge resonant converter on a single copper layer printed circuit board (PCB) that accepts a 385V input and generates an isolated 22.5V output up to 13.5A load. This design is comprised of the UCC256603 half-bridge LLC controller and UCC24612 synchronous rectifier (SR) controller, achieving a peak efficiency of 95.76%. PMP23463 achieves < 1% output ripple at no load and < 3% output voltage deviation during no load to full load transient.
