General Description

The NJW4152 is a buck converter with 40V/1A or 40V/600mA 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 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.
