Current Mode Control

Internal 1.8A MOSFET Switching Regulator IC for Buck Converter

GENERALDESCRIPTION

■ PACKAGE OUTLINE

The NJW4155 is a buck converter with 40V/1.8A MOSFET. It

corresponds to high oscillating frequency, and Low ESR Output

Capacitor (MLCC) within wide input range from 4.5V to 40V.

Therefore, the NJW4155 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.

NJW4155GM1

NJW4155DL3

It is suitable for supplying power to a CarAccessory, Office

Automation Equipment, Industrial Instrument and so on.
