Offline AC/DC 77W Quasi-Resonant Flyback Converter Reference Design

Overview

TopologyFlyback Converter
Input voltage165-275 V
Output 122 V / 3.5 A
IC revisionB

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

Remark: BOM is added with Schematic pdf.

  • 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
