NJW4617

Constant Current LED Driver with PWM Control

ꢀGENERAL DESCRIPTION

PACKAGE OUTLINE

The NJW4617 is a constant current LED Driver with PWM control.

45V resisting constant current control and PWM control circuit can

be offered with small package.

It can achieve luminance control multiple white or blue and red

LEDs. It can contribute to the reliability improvement of the system

because it has an overcurrent protection and thermal shutdown

circuit.
