Description
UC1874-1,-2 UC2874-1,-2 UC3874-1,-2 High Efficiency, Synchronous, Step-down (Buck) Controllers .
The UC3874 family of synchronous step-down (Buck) regulators provides high efficiency power conversion from an input voltage range of 4.
Features
* Operation to 36V Input Voltage
* Fixed Frequency Average Current Mode Control
* Standby Mode for Improved Efficiency at Light Load
* Drives External N-Channel MOSFETs for Highest Efficiency
* Sleep Mode Current < 50mA
* Complementary 1 Amp Outputs wi
Applications
* such as laptop computers, consumer products, communications systems, and aerospace which demand high performance and long battery life. The synchronous regulator replaces the catch diode in the standard buck regulator with a low Rds(on) N-channel MOSFET switch allowing for significant efficiency imp
