Description

This document is an engineering report that describes a universal-input 27 W 12 V and 5 V off-line flyback converter using the newest 5th generation Infineon QR CoolSET™ ICE5QR1680AG. It offers high-efficiency, lowstandby power with selectable entry and exit standby power options, a wider V CC operating range with fast start-up, robust line protection with input Over Voltage Protection (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 ICE5QR1680AG 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
