Switching Regulator IC for Boost Converter

Manufacturer's part number :


Manufacturer New Japan Radio

New Japan Radio

Description :

The NJW4130 is a boost converter with 40V MOSFET. It corresponds to high speed oscillating frequency, low input voltage (logic voltage) and Low ESR Output Capacitor (MLCC). Therefore, the NJW4130 can realize downsizing of an application with a few external parts. Also, it has a soft start function, over current protection and thermal shutdown circuit. It is suitable for supplying power to a LED, Portable Applications and so on.
