15-W, wide-input flyback reference design

Overview

TopologyFlyback Converter
Input voltage85-480 V
Output 124 V / 0.62 A
IC revisionC

Description

This reference design uses a UCC28742 flyback controller and an ATL432LI shunt reference to produce an isolated 24-V output capable of 0.625 A from an 85-V to 480-Vac input. All components are placed on one side of the board to reduce complexity and cost. The design can achieve 80% efficiency across various input conditions.

Features

  • Compact size (2" x 3.31") minimizes solution size area
  • Single-side assembly and 2-layer PCB for reduced manufacturing costs
  • Low noise output of less than 100-mV peak-to-peak voltage ripple for sensitive loads

Typical applications

  • Electricity meter
