30W 12V SMPS Evaluation board using ICE3BR0680JZ

This document is an engineering report of a universal input 30W 12V off-line flyback converter power supply utilizing IFX F3R80 CoolSET® ICE3BR0680JZ. The application demo board is operated in Discontinuous Conduction Mode (DCM) and is running at 65 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 high power system, etc. The ICE3BR0680JZ 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, 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 brownout feature, built-in soft start time, built-in and extendable blanking time, frequency jitter feature and external auto-restart enable, etc. The particular features needs to be stressed are the best-in-class low standby power and the good EMI performance
