NJW4131
Switching Regulator IC for Boost Converter
w/ 40V/1.4A or 40V/1A MOSFET
GENERAL DESCRIPTION
The NJW4131 is a boost converter with 40V/1.4A or 40V/1A
MOSFET. It corresponds to high oscillating frequency, and Low ESR
Output Capacitor (MLCC) within wide input range from 4.0V to 35V.
Therefore, the NJW4131 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 power supply to a Car Accessory, Office Automation
equipment, Industrial Instrument, LED and so on.
