FAST TURN-OFF INTELLIGENT RJECTIFIER
DESCRIPTION
The UTC USRC8802 is a fast turn-off intelligent rectifier for
Flyback converters that combines a 60V power switch that replaces
diode rectifiers for high efficiency. The chip regulates the forward
voltage drop of the internal power switch to about 70mV and turns it
off before the voltage goes negative.
FEATURES
* Supports DCM and Quasi-Resonant
* Flyback converters
* Integrated 10mΩ 60V Power Switch
* Compatible with Energy Star, 1W Standby Requirements
* VDD Range From 8V to 24V
* 70mV VDS Regulation Function
* Max 300kHz Switching Frequency
* Light Load Mode Function (1)with <300uA Quiescent Current
* Supports High-Side and Low-Side Rectification
* Power Savings of Up to 1.5W in a Typical Notebook Adapte
