Description

This document is an engineering report that describes a universal input 42 W, 12 V and 5 V off-line flyback converter using the latest 5th generation Infineon QR CoolSET™ ICE5QR0680AZ which offers high efficiency, low standby power with selectable entry and exit standby power options, wide VCC operating range with fast start up, robust line protection with input OVP and brownout and various modes of protection for a highly reliable system. This demo board is designed for users who wish to evaluate the performance of ICE5QR0680AZ and its ease of use.

Features

  • Novel quasi-resonant switching scheme
  • Rapid and adjustable start-up with cascode configuration
  • 2 level selectable active burst mode level
  • Built-in digital soft-start
  • Cycle by cycle peak current limitation
  • Digital frequency reduction with decreasing load for higher efficiency
  • Adjustable line input over-voltage and brown IN/OUT protection
  • VCC and CS pin short to ground protection
  • OLP, output short, output over-voltage, OTP with hysteresis and VCC over/under voltage protection
  • Auto-restart for all protection features

Typical applications

  • Offline aux SMPS for server, PC power, aircon, refrigerator and audio/ Offline main SMPS for adapter, set-top-box, water purifier, TV, industrial SMPS and POE
