DRAIN Internal N-MOSFET drain

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.
