15-W multi-output off-line flyback reference design

Overview

TopologyFlyback Converter
Input voltage85-265 V
Switching frequency100 kHz
Output 115 V / 0.05 A
Output 215 V / 1 A
Output 315 V / 0.05 A
IC revisionB

Description

This reference design takes a universal Vac input and creates three isolated 15-Vdc outputs. The main output can be loaded up to 1-A and achieves over 86% efficiency. The other isolated 15-V outputs can be loaded to 50-mA. These outputs have linear regulators to keep the voltages within 1% regardless of cross-loading conditions.

Features

  • Primary side regulated flyback to create multiple isolated outputs
  • Low profile >20mm design
  • 3% accuracy on 1-A output, 1% accuracy on 50-mA outputs

Typical applications

  • Standby Supply for TV and Desktop
  • USB-Compliant Adapters and Chargers for Consumer Electronics / White Goods
