High Efficiency 410W AC/DC Power Supply Reference Design


Design files


PMP11282 is a high-efficiency AC/DC power supply reference design with universal AC input and 24V/17A output. Interleaved transition mode PFC and LLC series resonant converter is applied for 24V/17A main power. A PSR Flyback with MOSFET integrated controller is applied as the auxiliary supply. 91.98% efficiency is achieved at low line and full load. 94.61% efficiency is achieved at high line and full load.

  • 410W PSU with interleaved transition mode PFC and LLC-SRC
  • 91.98% efficiency at 120VAC/60Hz and full load
  • 94.61% efficiency at 230VAC/50Hz and full load
  • 125mm x 225mm board dimension
  • Test report is available
  • Conduction EMI test results included
