IC revision1.0

Description

This document is an engineering report that describes a universal-input 14 W 15 V 5 V off-line non-isolated Flyback converter using the latest fifth-generation Infineon Fixed Frequency (FF) CoolSET™ ICE5AR4770AG, 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 Over Voltage Protection (OVP) and various protection modes for a highly reliable system. This demo board is designed for users who wish to evaluate ICE5AR4770AG in terms of optimized efficiency, thermal performance and EMI.

Features

  • Flyback topology with dual non-isolated output
  • 100kHz switching frequency with discontinuous current mode design
  • Wide-range input from 85~300VAC with line over-voltage protection at 320VAC
  • Output #1: 15V/0.83A
  • Output #2: 5V/0.4A

Typical applications

  • Offline SMPS, adapter, main power set-top-box, water/air purifier and TV, auxiliary power for air conditioning, refrigerator, server, PC power and audio
