NJW4154 - Automotive Switching Regulator

General Description

The NJW4154 is a buck converter with 40V/3A MOSFET.

It corresponds to high oscillating frequency, and Low ESR Output Capacitor (MLCC) within wide input range from 4.5V to 40V.

Therefore, the NJW4154 can realize downsizing of applications with a few external parts so that adopts current mode control.
