Design files

Overview

PMP20583 is a primary-side regulated flyback reference design which provides a ground referenced 5V output and an isolated 5V output at up to 80mA each from an input voltage of 37V to 125V. This design uses the UCC28700-Q1 flyback controller for constant voltage and constant current control of the output. Variable frequency operation minimizes standby power at no load. Features include quasi-resonant valley switching for highest efficiency and frequency dithering to improve EMI performance.

Features
  • Primary-side regulation
  • Constant-voltage and constant-current operation
  • Less than 10mW no load power
  • Frequency dithering
  • One isolated and one ground referenced output
