UC3874-2 Overview
The UC3874 family of synchronous step-down (Buck) regulators provides high efficiency power conversion from an input voltage range of 4.5 to 36 volts. The UC3874 is tailored for battery powered applications such as laptop puters, consumer products, munications systems, and aerospace which demand high performance and long battery life. The synchronous regulator replaces the catch diode in the standard buck regulator...
