Switching Regulator IC for Buck Converter

Current Mode Control w/ 40V/3A MOSFET

ꢀGENERAL DESCRIPTION

■ PACKAGE OUTLINE

The NJW4154 is a buck converter with 40V/3A MOSFET. It

corresponds to high oscillating frequency, and Low ESR Output

Capacitor (MLCC) within wide input range from 4.5V to 40V.

Therefore, the NJW4154 can realize downsizing of applications

with a few external parts so that adopts current mode control.

Also, it has a soft start function, external clock synchronization,

over current protection and thermal shutdown circuit.

NJW4154GM1

NJW4154DL3

It is suitable for supplying power to a Car Accessory, Office

Automation Equipment, Industrial Instrument and so on.
