Ultra-Wide Input Voltage Range PSR Flyback Converter Reference Design

Overview

TopologyFlyback Converter
Input voltage25-520 V
Output 128 V / 0.71 A
IC revisionB

Description

The PMP10200 reference design uses the UCC28700 primary-side regulated quasi-resonant flyback controller to generate a 28V output from an DC input. The input voltage range is between 25VDC and 520VDC. It is a low cost solution because no optocoupler is needed to regulate the output voltage.

Features

  • Quasi-Resonant Flyback Topology
  • Ultra-Wide Input Voltage Range
  • High Efficiency
  • No Need For an Optocoupler
  • This reference design was built and tested and the test report is included
