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.
