Download Datasheet

Description

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.It is suitable for boost application to a Car Accessory, Office Automation Equipment, Industrial Instrument and so on
