Pin Description
Pin Number Pin Name Function
1 C1-
Flying capacitor 1 negative terminal. The flying capacitor should be connected as close
to this pin as possible
2 C2-
Flying capacitor 2 negative terminal. The flying capacitor should be connected as close
to this pin as possible
3 C2+
Flying capacitor 2 positive terminal. The flying capacitor should be connected as close
to this pin as possible
4 C1+
Flying capacitor 1 positive terminal. The flying capacitor should be connected as close
to this pin as possible
5 AGND Analog ground
6 PGND Power ground
7 VIN Supply voltage input
8 EN
Enable control input. Logic high enables the IC; while logic low forces the IC into
shutdown mode. It is used for digital dimming by applying a pulse signal on it.

D5 ~ D1
Current sink for WLED5, 4, 3, 2, 1. Connect the cathode of WLEDs to these pins. If
not used, these pins must be connected with VIN
14 VOUT2 Output pin 2. It powers 5 channels current sink
15 NC No connection
16 VOUT1
Output Pin 1. It’s the charge pump output. The output capacitor should be placed
closely to this pin
