NJW4161
MOSFET Drive Switching Regulator IC for Buck Converter
GENERAL DESCRIPTION
The NJW4161 is a MOSFET Drive switching regulator IC for Buck Converter that operates wide input range from 3.1V to 40V. It can provide large current application because of built-in highly effective Pch MOSFET 10V drive circuit.
There are two types, Hiccup type and Latch type, of over current protection version.
It is suitable for logic voltage generation from high voltage that Car Accessory, Office Automation Equipment, Industrial Instrument and so on.
