NJW4140
MOSFET Drive Switching Regulator IC for Boost / Fly-back Converter
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.
It is suitable for boost/fly-back application such as Car
Accessory, Office Automation Equipment, Industrial Instrument
and so on.
