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.  PACKAGE OUTLINE NJW4615AF1 (SOT-23-6-1)  FEATURES  Supply Voltage Range 2.5V to 35V  Output Voltage  Output Current  Output Current Accuracy VLED=35V max.
