Overview

NJW4155 Current Mode Control Internal 1.
8A MOSFET Switching Regulator IC for Buck Converter GENERAL DESCRIPTION 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.
It is suitable for supplying power to a Car Accessory, Office Automation Equipment, Industrial Instrument and so on.
FEATURES Current Mode Control External Clock Synchronization Wide Operating Voltage Range 4.
5V to 40V Switching Current 2.
7A min.
PWM Control Built-in Compensation Circuit Correspond to Ceramic Capacitor (MLCC) Oscillating Frequency 450kHz typ.
(A, C ver.
) 300kHz typ.
(B ver.
