NJW4128 Switching Regulator IC for Buck Converter Current Mode Control w/ 40V/2.5A MOSFET GENERAL DESCRIPTION The NJW4128 is a buck converter with 40V/2.5A MOSFET. It corresponds to high oscillating frequency, and Low ESR Output Capacitor (MLCC) within wide input range from 4.5V to 40V. Therefore, the NJW4128 can realize downsizing of applications with a few external parts so that adopts current mode control. Also, it has a soft start function, external clock synchronization, over current protection and thermal shutdown circuit. It is suitable for supplying power to a Car Accessory, Office Automation Equipment, Industrial Instrument and so on. ■ PACKAGE OUTLINE NJW4128GM1 FEATURES Current Mode Control External Clock Synchronization Wide Operating Voltage Range 4.
