NJW4196

NJW4196 Internal 3.5A MOSFET Switching Regulator IC for Buck Converter 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. ■ PACKAGE OUTLINE NJW4196GM1 FEATURES Fast supply voltage transient response from a reduced voltage External Clock Synchronization Wide Operating Voltage Range 4.45V to 40V Switching Current 5A min.
