Feedback input. The control loop regulates the current in such a way that the average
FB
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
SLOPE Capacitor for slope control
DISC
Load disconnection flag (open drain)
Exp-pad Internally connected to ground.
