Internal N-MOSFET drain
Internal N-MOSFET source. Reference voltage is 100 mV. An external resistor between
SOURCE and GND pins sets different current levels for different application needs
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
Capacitor for slope control
Load disconnection flag (open drain)
Internally connected to ground
