NJW4154
Switching Regulator IC for Buck Converter
Current Mode Control w/ 40V/3A MOSFET
GENERAL DESCRIPTION
The NJW4154 is a buck converter with 40V/3A MOSFET. It
corresponds to high oscillating frequency, and Low ESR Output
Capacitor (MLCC) within wide input range from 4.5V to 40V.
Therefore, the NJW4154 can realize downsizing of applications
with a few external parts so that adopts current mode control.
Also, it has a soft start function, external clock synchronization,
over current protection and thermal shutdown circuit.
It is suitable for supplying power to a Car Accessory, Office
Automation Equipment, Industrial Instrument and so on.
