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.
No connection (AP3606 only)
Current sink for WLED6 and WLED5. Connect the cathode of WLEDs to these
pins. If not used, these pins must be connected with VIN (AP3607 only)
Current sink for WLED4, 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 4 channels current sink (AP3606) and 6 channels current
sink (AP3607)
Output Pin 1. It’s the charge pump output. The output capacitor should be placed
closely to this pin
