3 EN Shutdown pin
4 DRAIN Internal N-MOSFET drain
5FB
Feedback input. The control loop regulates the current in such a way that the average
voltage at the FB input is 100 mV (nominal). The cathode of the LED and a resistor to
ground to set the LED current should be connected at this point
6 GND Ground
7 N.C. In order to guarantee the device works properly it is mandatory to leave this pin floating
8 DISC Load disconnection flag (open drain)
Exp-pad Internally connected to ground
