Description
Connect a R_SET resistor between this pin and GND. R_SET=7.5K, set I_LED to 20mA.
(Recommended)
Current sink output #5. If not used, connected to V_IN or floating.
Current sink output #4. If not used, connected to V_IN or floating.
Current sink output #3. If not used, connected to V_IN or floating.
Current sink output #2. If not used, connected to V_IN or floating.
Current sink output #1. If not used, connected to V_IN or floating.
Power GND.
