This AC to DC power supply design for TV application provides 12-V, 5-A and 150-V, 0.8-A output from universal AC voltage (90 Vac to 264 Vac). The design uses CRM/DCM PFC controller UCC28056, and LLC controller UCC256404 with enhanced burst mode which enabled for low standby power and smaller audible noise. The design achieves <250-mW standby power with 150-mW load and >93% peak efficiency at 230-Vac input.
