NJW4150
Internal 34V MOSFET Switching Regulator IC for Buck Converter
GENERAL DESCRIPTION
The NJW4150 is a switching regulator IC for buck converter with
34V, 450mA MOSFET. It corresponds to high frequency oscillating,
wide input voltage and Low ESR Output Capacitor (MLCC).
Therefore, the NJW4150 can realize downsizing of applications
with a few external parts.
Also, it has a soft start function, over current protection and
thermal shutdown circuit.
It is suitable for power supply circuit of Car Accessory, Office
Automation Equipment, Industrial Instrument and so on.
