12W 5V SMPS Evaluation Board with CoolSET?? ICE3AR4780JZ
Universal input 12W 5V off-line flyback converter power supply board utilizing CoolSET?
ICE3AR4780JZ. The application demo 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.? 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 faults (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 need to be stressed are the best-in-class low standby power and the good EMI performance.
