NJW4128 Datasheet - New Japan Radio

NJW4128 Switching Regulator

The NJW4128 is a buck converter with 40V/2.5A MOSFET. It corresponds to high oscillating frequency, and Low ESR Output Capacitor (MLCC) within wide input range from 4.5V to 40V. Therefore, the NJW4128 can realize downsizing of applications with a few external parts so that adopts current mode contro.
