This reference design is a universal line 85-265VAC input to 80V/50W power supply in a small form-factor, cost-effective design. It uses the UCC28704 controller. The design features an optional FET-startup circuit for low standby power and achieves over 91% efficiency. The PMP20545 Board is a 4-layer, 1-oz copper weight per layer, 80mm x 60mm board with 24mm max component height. This design is Non-isolated.
Remark: BOM and test-result PDF are added.
