Switching Regulator IC for Boost Converter

Manufacturer's part number :

NJW4132U2-B

Manufacturer New Japan Radio

New Japan Radio

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.
