Description

The NJW4196 is a buck converter with 40V/3.5A MOSFET. It improves transient response at recovering from voltage drop compare with conventional current mode products. Therefore the NJW4196 provides excellent stable regulation even under condition of large voltage fluctuations. Oscillating frequency can be synchronized with an externally input clock. Also, it has a soft start function, an over current protection and a thermal shutdown circuit. It is suitable for power supply for Car Accessory, Office Automation Equipment, Industrial Instrument and so on.

Applications


  • Car accessory
  • Industrial equipment
  • OA equipment
