NJW4132
Switching Regulator IC for Boost Converter
Current Mode Control w/ 45V/1.75A MOSFET
GENERAL DESCRIPTION
The NJW4132 is a boost converter with 45V/1.75A MOSFET. It
corresponds to high oscillating frequency, and Low ESR Output
Capacitor (MLCC) within wide input range from 4.5V to 40V.
Therefore, the NJW4132 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 boost application to a Car Accessory, Office
Automation Equipment, Industrial Instrument and so on.
