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 latest fifth-generation Infineon Fixed Frequency (FF) CoolSET™ ICE5GR1680AG, which offers high-efficiency, low-standby power with selectable entry and exit standby power option, wide VCCoperating range with fast start-up, robust line protection with input Over Voltage Protection (OVP), and various modes of protection for a highly reliable system. This demo board is designed for users who wish to evaluate the performance of ICE5GR1680AG in terms of optimized efficiency, thermal performance and EMI.
Features
- Flyback topology with dual isolated output
- 125kHz switching frequency with discontinuous current mode design
- Wide-range input from 85~300VAC with line over-voltage protection at 320VAC
- Output #1: 12V/2.16A
- Output #2: 5V/0.2A
Typical applications
- Offline SMPS, adapter, main power for set-top-box, water/air purifier and TV, auxiliary power for air conditioning, refrigerator, server, PC power and audio
