Infineon Technologies ICE3AR2280VJZ

Description

This document is an engineering report of a universal input 20 W 5 V off-line flyback converter power supply utilizing F3R80 CoolSET™ ICE3AR2280VJZ. The application evaluation board is operated in Discontinuous Conduction Mode (DCM) and is running at 100 kHz switching frequency. It has a single output voltage with secondary side control regulation. It is especially suitable for small power supply such as DVD player, set-top box, game console, charger and auxiliary power of white goods, server, PC and high power system, etc. The ICE3AR2280VJZ is the latest version of the CoolSET™. Besides having the basic features of the F3R CoolSET™ such as Active Burst Mode, propagation delay compensation, soft gate drive, auto restart protection for major fault (VCC over voltage, VCC under voltage, adjustable input OVP, over temperature, over-load, open loop and short opto-coupler), it also has the BiCMOS technology design, selectable entry and exit burst mode level, adjustable AC line input over voltage protection feature, built-in soft start time, built-in and extendable blanking time and frequency jitter feature, etc. The particular features are the Best-in-Class low standby power and the good EMI performance.
