NJW4150A - Internal 40V MOSFET Switching Regulator

General Description

The NJW4150A is a buck converter with 40V/300mA MOSFET.

It corresponds to high oscillating frequency, and Low ESR Output Capacitor (MLCC) within wide input range from 6.2V to 40V.

Therefore, the NJW4150A can realize downsizing of an application with a few external parts.
