NJW4152 - (Automotive) Switching Regulator

Download the NJW4152 datasheet PDF. This datasheet also covers the NJW4152-1 variant, as both devices belong to the same (automotive) switching regulator family and are provided as variant models within a single manufacturer datasheet.

Description

The NJW4152 is a buck converter with 40V/1A MOSFET.

It corresponds to high oscillating frequency, and Low ESR Output Capacitor (MLCC) within wide input range from 4.6V to 40V.

Therefore, the NJW4152 can realize downsizing of an application with a few external parts.
