Automotive NJW4152
Switching Regulator IC for Buck Converter
with 40V/1A MOSFET
GENERAL 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.
Also, it has a soft start function, an over current protection and a thermal
shutdown circuit. Moreover there is an automotive for extended operating
temperature range version.
It is suitable for logic voltage generation from high voltage that Car
Accessory, Office Automation Equipment, Industrial Instrument and so on.
