ICE3AR4780JG

SMPS IC 800V 100kHz DSO-12 SMD

Description:

 

The CoolSET™-F3R80 is an enhanced 800 V MOSFET version of ICE3BRxx65J CoolSET™-F3R 650V in DSO- 16/12 package. In particular it is running at 100 kHz, implemented with brownout feature, installing 800 V CoolMOS™ with startup cell. It targets for the low power SMPS with increased MOSFET voltage margin requirement such as Off-Line battery adapters, DVD R/W, DVD Combi, Blue ray, set top box, auxiliary power supply for White Goods, PC and server, etc. In summary, the CoolSET™ F3R80 provides good voltage margin of MOSFET, lowest standby power, selectable burst level, reduced output ripple during burst mode, reliable output with brownout feature, accurate maximum power control for both maximum power and burst power, low EMI with frequency jittering and soft gate drive, built-in and flexible protections, etc. Therefore, CoolSET™ F3R80 is a complete solution for the low power SMPS application.
