General Description

The NJW4616 is a constant current LED driver with PWM dimming control. The output current can be set by external sensing resister, and the NJW4616 can set up to 300mA. Because the withstand voltage of the output (LED) pin is 40V, it can series-connect the LED depending on forward voltage of the LED. The LED dimming control can be regulated via PWM duty cycle. It is suitable for back light, light source and so on.
