NJW4119 Datasheet Buck Switching Regulator

Manufacturer: New Japan Radio

Overview: NJW4119 BUCK SWITCHING REGULATOR WITH VOLTAGE CORRECTION CIRCUIT.

General Description

The NJW4119 is a buck switching regulator with voltage correction circuit that delivers up to 2.4 A of output current.

The voltage correction (cable drop pensation) raises the output voltage in proportion to the load current.

This function corrects the voltage drop due to cable or writing board resistance.
