TPS68470: WLED unused case

Part Number: TPS68470

Hi,

We should connect both WLED_SW and WLED_GND to ground if WLED function is not used.  May we know what is the side effect if the pins are floating?

THanks!

Antony

    Hi Antony,

    Floating the pins may allow noise to couple into the device, and we can not say exactly how this could affect the part.

    Grounding these pins prevents this uncertainty, and ensures consistent conditions while the device is operating.

    Best Regards,
