TPS65987D: If PP_HV1 is not used, does it need a bypass cap?

cpu utopia

Part Number: TPS65987D

I'm not using the SINK PATH (PP_HV1).

Is there any issue with this having a cap to GND?

Do I need to ground the pin and remove the bypass cap?

Hello,

If you want to save the capacitor, GND this pin. There is no issue with keeping Cap on this pin when unused.

Tnx

Thanks for the response.

I just wanted to clarify that this pin is not grounded so it's floating @ DC.

It does have a CAP to GND (so I could potentially replace the CAP with a 0 ohm RES to honor the "GND if unused" statement in the datasheet)

Alternatively, if I leave this pin floating would there be detrimental effects?

Hi,

I would recommend you to GND this pin to keep it in a defined state.

Thanks
