Pin Function
Power Supply Pin
Output Current Setting pin. Connect a resistor from ISET to GND to set the
LED bias current. I_SET=1.2V/R_SET
Ground Pin
Output Stage Enable Control pin. High enable the output pin. It can be left
floating for normally on.
Output pin. Sink current is decided by the current on R_SET connected to I_SET
pin. I_OUT=500 x I_SET=500 x 1.2V/R_SET
