12-Watt Magnetically Resistant Quasi-Resonant Flyback Reference Design

Overview

TopologyFlyback Converter
Input voltage90-490 V
Switching frequency80-130 kHz
Output 14 V / 2 A
Output 210 V / 0.4 A
IC revisionB

Description

Customer specific quasi-resonant flybackThis reference design is a quasi-resonant flyback developed to be resistant to large magnetic fields near the transformer. It has a regulated 4 Volt output that can handle up to 2 A of current and secondary 10 V output that can handle 0.4 A.

Features

  • 90 VAC to 490 VAC input to 4 V/2 A isolated output
  • Secondary output of 10 V/ 400 mA
  • Iron Powder Transformer for improved magnetic resistance
  • Topology designs to run at a low frequency to further increase magnetic resistance

Typical applications

  • Industrial and Medical AC-to-DC Power Supplies
  • AC-to-DC Power Supply for Appliances
  • Smart Electricity Meters / Bias Supply for UPS, Server PSU
  • Power Supply for Cable Modem, Television, Set-Top Box, and Wireless Routers
