PMP11303 is high-efficiency AC/DC power supply reference design with universal AC input and 25V/13.5A and 12V/1A outputs. LLC+PFC combo IC UCC29950 is applied for the main power stages with 25V/13.5A output while UCC28730 is applied for the auxiliary power with 12V/1A output. This design has low no load power comsumption (152mW@230VAC) and over 93% peak efficiency. This design also meet 80PLUS Gold requirement for 115VAC Internal power supplies.
