Description

The NJW4142 is a MOSFET drive switching regulator IC for boost / fly-back converters that operates wide operating voltage range from 2.5V to 40V. The internal Nch MOSFET driver circuit provides high efficiency driving, makes this device ideal for high output current applications. The protection function is equipped pulse-by-pulse overcurrent detection to limits the switching current at overload. The NJW4142 is suitable for boost / fly-back applications such as industrial instruments and so on.

Applications

  • Consumer Electronics
  • Industrial Instruments
  • Boost Converter for Small to Middle Range Power Supplies
