LP5562: Unused WLED pin

Part Number: LP5562


Hi All:

I'm currently working on a design which uses the LP5562, but I am only driving an RGB LED and do not have a need for the WLED pin. For maximum power savings, should I leave the pin floating, or connect it to GND or VDD? I apologize in advance if this information is contained in the datasheet; I have not been able to find it through my reading of it.

Thanks,

Yan
