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.
