Function
Biases the open-Drain output MOSFET
Feedback pin
Open-Drain LED driver output
Current sense pin. LED current sensing resistor should be connected from here to GND
Compensation pin. Connect COMP pin to REXT pin and insert a 1nF ceramic capacitor from COMP
pin to FB pin for improved transient stability
Ground reference point for setting the LED current
