NJW4616
Constant Current LED Driver with PWM Control
GENERAL DESCRIPTION
The NJW4616 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.
