Switching Regulator IC for Boost Converter

Current Mode Control w/ 45V/1.75A MOSFET

ꢀGENERAL DESCRIPTION

■ PACKAGE OUTLINE

The NJW4132 is a boost converter with 45V/1.75A MOSFET. It

corresponds to high oscillating frequency, and Low ESR Output

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

Therefore, the NJW4132 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.

NJW4132U2

It is suitable for boost application to a Car Accessory, Office

Automation Equipment, Industrial Instrument and so on.
