NJW4160 Series

Switching Regulator IC for Buck Converter External MOSFET driving

Download Datasheet

Description

The NJW4160 is a MOSFET Drive switching regulator IC for Buck Converter that operates wide input range from 3.0V to 35V. It can provide large current application because of built-in highly effective Pch MOSFET drive circuit. Built-in pulse-by-pulse current detecting type over current protection limits the output current at over load. It is suitable for logic voltage generation from high voltage that Car Accessory, Office Automation Equipment, Industrial Instrument and so on.
