Infineon Technologies ICE3AR1080VJZ | Demoboard AN-EVAL ICE3AR1080VJZ

Description

This document is an engineering report of a universal input 34 W 12 V off-line flyback converter power supply utilizing F3R80 CoolSET™ ICE3AR1080VJZ. 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 ICE3AR1080VJZ 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, overload, 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.
