Key Document


The PMP10150 reference design uses the UCC28600 quasi-resonant flyback controller to generate a 12V and a -8.5V output from an universal AC input. An optocoupler is used to regulate the 12V output.

  • -8.5V output referenced to primary side, 12V output referenced to secondary side
  • 30W output power
  • Peak efficiency of 84%
  • Fully built and tested design
  • Board dimensions: 116mm x 65mm
