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
Ground
In order to guarantee the device works properly it is mandatory to leave this pin floating
