NJW4153 - Switching Regulator

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.

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. FEATURES Current mode Control Maximum Rating Input Voltage 45V Wide Operating Voltage Range 4.6V to 40V Switching Current 1.4A min.
