2.2μF (minimum) bypass capacitor must be connected from Vcc to GND pin.

C+

4

Positive terminal of external pump capacitor.

C-

5

Negative terminal of external pump capacitor.

EN/SET

6

PCC serial input for enabling/disabling LEDs and setting current levels.

GND

7

Ground.

D5

8

LED output; if not used, connect to ground to avoid noise coupling.
