ICE3BR0680JZ

The ICE3BR0680JZ (CoolSET-F3R80) is an enhanced 800V MOSFET version of ICE3BRxx65J (CoolSET-F3R 650V) in DIP-7 package. The PWM controller is based on F3R 650V with some new and enhanced features. In particular it is a device running at 65KHz, implemented with brownout features, installing 800V CoolMOS with startup cell and packaged into DIP-7. 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 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.
