General Description

The NJW4140 is a MOSFET drive switching regulator IC for Boost/Fly-back Converter that operates wide input range from 3V to 40V.

It can provide large current application because of built-in highly effective Nch MOSFET drive circuit.

Built-in pulse-by-pulse current detecting type over current protection limits the output current at over load.
