Description

The PMP10168 reference design uses the UCC28710 primary-side regulated quasi-resonant flyback controller to generate a 12V and a 5V output from an universal AC input. It is a low cost solution because no optocoupler is needed to regulate the output voltages.

Features
  • 5V output referenced to primary side, 12V output referenced to 2ndary side (isolated)
  • 12W output power
  • Peak efficiency of 82%
  • No Need For an Optocoupler
  • Fully built and tested design
  • Board dimensions: 72mm x 38mm
