3-Phase Input Valley Switching Flyback With Two Outputs Reference Design

Overview

TopologyFlyback Converter
Input voltage332-459 V
Output 123 V / 1 A
IC revision1

Description

This reference design uses the UCC28742 flyback controller to generate two outputs (23 V at 1.0 A, 5.0 V at 0.15 A) from a 3-phase input. The UCC28742 uses an optical coupler to regulate the output and to improve transient response. The valley-switching technique reduces switching losses and keeps the efficiency high

Typical applications

  • water heater
