EVAL-3AR0680VJZ

概要

30W 12V SMPS evaluation board with ICE3AR0680VJZ

Universal input 30W 12V off-line flyback converter power supply utilizing control IC with integrated MOSFET CoolSET™ ICE3AR0680VJZ. 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 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 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.
