MOSFET Drive Switching Regulator IC for Boost / Fly-back Converter
-
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.
Applications
- Automotive ECU
- Industrial control equipment
