Description

The PMP10121 reference design uses the UCC28600 quasi-resonant flyback controller to generate 22V @ 3.5A from an AC input. This flyback converter is not isolated and no optocoupler is needed for regulation.

Features
  • Quasi-Resonant Flyback Topology
  • Four Point Average Efficiency  = 90.3% (Vin=230VAC)
  • 10% Load Efficiency = 89% (Vin=230VAC)
  • No Need For an Optocoupler
  • This reference design was built and tested and the test report is included
