NJW4153 - Automotive Switching Regulator

General Description

The NJW4153 is a buck converter with 40V/1A MOSFET.

It corresponds to high oscillating frequency, and Low ESR Output Capacitor (MLCC) within wide input range from 4.6V to 40V.

Therefore, the NJW4153 can realize downsizing of applications with a few external parts so that adopts current mode control.

Automotive NJW4153 Switching Regulator IC for Buck Converter Current Mode Control w/ 40V/1A MOSFET  GENERAL DESCRIPTION The NJW4153 is a buck converter with 40V/1A MOSFET. It corresponds to high oscillating frequency, and Low ESR Output Capacitor (MLCC) within wide input range from 4.6V to 40V. Therefore, the NJW4153 can realize downsizing of applications with a few external parts so that adopts current mode control. Also, it has a soft start function, an over current protection and a thermal shutdown circuit. It is suitable for power supply circuit of Micro Processor, DSP and so on that need fast transient response. ■ PACKAGE OUTLINE NJW4153U2-A-T1  FEATURES  Current mode Control  Maximum Rating Input Voltage 45V  Wide Operating Voltage Range 4.
