1
VOUT  
Charge Pump Output. A 2.2 µF capacitor to ground is required on this pin. Connect VOUT to the anodes of all  
the LEDs.

C2+  
ISET  
Flying Capacitor 2 Positive Connection.  
Bias Current Set Input. The current flowing through RSET, ISET, is gained up by 120 to give the ILED current.  
Connect RSET to GND to set the bias current as VSET/RSET. Note that VSET = 1.18 V.  
4–9  
FB1–FB6  
LED1–LED6 Cathode Connection and Charge Pump Feedback. The current flowing in these LEDs is 120 times  
the current flowing through RSET, ISET. When using fewer than six LEDs, this pin can be left unconnected or  
connected to GND.
