NJW4615A
Constant Current LED Driver with PWM Dimming Control
GENERAL DESCRIPTION The NJW4615A is a constant current LED driver with PWM dimming control. Driving roads up to 100mA, the output current level can be adjusted via an external resistor.
Because the withstand voltage of the LED pin is 35V, it can series-connect the LED depending on forward voltage of the LED. The LED brightness control can be regulated via PWM duty cycle. It suitable for back light, light source and so on.
