UTC USRC8801 FAST TURN-OFF INTELLIGENT CONTROLLER
| Previous | 20 / 182 | Next |
FAST TURN-OFF INTELLIGENT CONTROLLER
DESCRIPTION
The USRC8801 is a Low-Drop Diode Emulator IC that, combined with an external switch replaces Schottky diodes in high-efficiency, Flyback converters. The chip regulates the forward drop of an external switch to about 70mV and switches it off as soon as the voltage becomes negative. SOT-25 1 3 5 2 4
FEATURES
* Works with both Standard and Logic Level FETS
* Compatible with Energy Star, 1W Standby Requirements
* VDD Range From 8V to 24V
* 70mV VDS Regulation Function
* Fast Turn-off Total Delay of 20ns
* Max 400kHz Switching Frequency
* <3mA Low Quiescent Current
* Supports CCM, DCM and Quasi-Resonant Topologies
* Supports High-side and Low-side Rectification
* Power Savings of Up to 1.5W in a Typical Notebook Adapter
APPLICATION
* Industrial Power Systems
* Distributed Power Systems
* Battery Powered Systems
* Flyback Converters
