EVALSF3R-ICE3AR2280CJZ - Infineon Technologies

概要

20W 5V SMPS Evaluation Board with CoolSET™ ICE3AR2280CJZ

Universal input 20W 5V off-line flyback converter power supply utilizing CoolSET™ ICE3AR2280CJZ. The application demo board is operated in Continuous and Discontinuous Conduction Mode (CCM & DCM) and is running at 100 kHz switching frequency. It has a single output voltage with secondary side control regulation. The ICE3AR2280CJZ is the enhanced version of ICE3ARxx80JZ (CoolSET® -F3R80), the major new featrures includes slope compensation for continuous conduction mode (CCM), fast AC reset after latch enabled, fixed voltage brownout detect/reset. Besides having the basic features of the 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, built-in soft start time, built-in blanking time, frequency jitter feature and external latch enable, etc. The particular features need to be stressed are 800V MOSFET,CCM/DCM operation, fixed voltage Brownout detect/reset, fast AC reset, the best-in-class low standby power and the good EMI performance.
