Overview

TopologyFlyback Converter
Input voltage85-265 V
Output 124 V / 5 A
IC revisionA

Description

120 W isolated flyback power supply for appliances using LinkSwitch-HP (LNK6779E)

Features

Primary-side regulated isolated flyback converter with ±5% regulation

  • 132 kHz switching frequency for small transformer and output filter size
  • Full load Continuous Conduction Mode (CCM) operation for improved efficiency andreduced output capacitor ripple current
  • <70 mW no-load input power at 230 VAC
  • Multimode operation maximizes efficiency across load range
  • Extensive protection including OVP, OTP, brown-in/out, line overvoltage, and lostregulation (auto-restart)
  • 88% full load efficiency @ 115 VAC and 90% full load efficiency @ 230 VAC
  • Easily meets DoE 6 efficiency requirements of 88% average efficiency (end of cable)
  • Class B Conducted EMI with > 6 db margin

Typical applications

  • Appliances
