30W 12V SMPS Evaluation Board with CoolSET™ ICE3BR0680JZ

Universal input 30W 12V off-line flyback converter power supply utilizing 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. Besides having the basic features of the 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.
