High Efficiency 350W AC/DC Power Supply Reference Design


Design files


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.

  • Conduction EMI test results included
  • Meet 80PLUS Gold for 115VAC internal power supplies
  • 25V/13.5A and 12V/1A dual outputs
  • 122mm x 200mm board dimension
  • Test report is available
  • Over 98% peak PFC efficiency at high line
