NJW4153

Switching Regulator IC for Buck Converter

Current Mode Control w/ 40V/1A MOSFET

ꢀGENERAL DESCRIPTION

■ PACKAGE OUTLINE

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.

NJW4153U2

It is suitable for power supply circuit of Micro Processor, DSP

and so on that need fast transient response.
