EVALSF3R-ICE3BR4765JG

概要

10W 12V SMPS Evaluation Board with CoolSET™ ICE3BR4765JG 

Universal input 12V 10W off-line flyback converter power supply utilizing integrated power management IC ICE3BR4765JG. The application demo board is operated in Discontinuous Conduction Mode (DCM) and is running at 65 kHz switching frequency. It has a one output voltage with secondary side control regulation. Besides having the basic features of the F3 CoolSET® such as Active Burst Mode, propagation delay compensation, soft gate drive, auto restart protection for serious fault (Vcc over voltage protection, Vcc under voltage protection, over temperature, over-load, open loop and short opto-coupler), it also has the BiCMOS technology design, built-in soft start time, built-in and extendable blanking time, frequency jitter feature with built-in jitter period 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.
