Description
The ICE3AR4780JZ (CoolSET
MOSFET version of ICE3BRxx65J (CoolSET
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 100KHz, implemented with brownout
features, installing 800V CoolMOS
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
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
low power SMPS application.
