NJW4150A
Internal 40V MOSFET Switching Regulator IC for Buck Converter
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.
Also, it has a soft start function, an over current protection and a
thermal shutdown circuit.
It is suitable for logic voltage generation from high voltage that
Car Accessory, Office Automation Equipment, Industrial Instrument
and so on.
