NJW4131

Switching Regulator IC for Boost Converter

w/ 40V/1.4A or 40V/1A MOSFET

ꢀGENERAL DESCRIPTION

■ PACKAGE OUTLINE

The NJW4131 is a boost converter with 40V/1.4A or 40V/1A

MOSFET. It corresponds to high oscillating frequency, and Low ESR

Output Capacitor (MLCC) within wide input range from 4.0V to 35V.

Therefore, the NJW4131 can realize downsizing of an application

with a few external parts.

NJW4131GM1-A

Also, it has a soft start function, an over current protection and a

thermal shutdown circuit.

(HSOP8)

It is suitable for power supply to a Car Accessory, Office Automation

equipment, Industrial Instrument, LED and so on.
