NJW4161 MOSFET Drive Switching Regulator

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 protec.
