General Description
The NJW4196 is a buck converter with 40V/3.5A MOSFET. The transient response when a supply voltage rises from a reduced voltage is improved than conventional current mode products, therefore the NJW4196 provides stable regulation characteristic even if application which an operating voltage fluctuates. External Clock Synchronization function synchronizes oscillating frequency with external clock input. Also, it has a soft start function, an external clock synchronization, an over current protection and a thermal shutdown circuit. It is suitable for supplying power to a Car Accessory, Office Automation Equipment, Industrial Instrument and so on.
