NJW4615
Constant Current LED Driver with PWM Control
GENERAL DESCRIPTION
The NJW4615 is a constant current LED with PWM control. 35V
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.
The NJW4615 is suit for an amusement, home audio,etc.
