12W auxiliary SMPS for energy-efficient refrigerator using ICE5QR2270AZ

Overview

TopologyFlyback Converter
Input voltage85-264 V
Output 112 V / 1 A
IC revision1

Description

This document is a reference design for a 12 W auxiliary SMPS for a refrigerator with the latest fifth-generation Infineon QR CoolSET™ ICE5QR2270AZ. The power supply is designed with a universal input compatible with most geographic regions and isolated output (+12 V/1 A) on a single-layer PCB, as typically employed in most home appliances.

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
