Description

The NJW4131A 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.
