Function
Flying capacitor 1 negative terminal. The flying capacitor should be connected as close
to this pin as possible
Flying capacitor 2 negative terminal. The flying capacitor should be connected as close
to this pin as possible
Flying capacitor 2 positive terminal. The flying capacitor should be connected as close
to this pin as possible
Flying capacitor 1 positive terminal. The flying capacitor should be connected as close
to this pin as possible
Analog ground
Power ground
Supply voltage input
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.
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
Output pin 2. It powers 5 channels current sink
No connection
Output Pin 1. It’s the charge pump output. The output capacitor should be placed
closely to this pin
