TPS3711: SENSE Bypass cap

Yuto Sakai

Part Number: TPS3711

Hi,

A bypass capacitor of 1 to 10 nF is recommended for the SENSE pin.
Is there a problem with placing a 10nF or more capacitor?
I think that there is a possibility of oscillation.

Yuto-san,

We recommend using the values specified in the data sheet. In theory, it shouldn't be an issue if you used a 10nF or higher capacitor on the SENSE pin.

Is there any reason why you want to use a larger capacitance?

Hi Krysitan-san,

Customers want to try a capacitor of about 1 to 10 μF to reduce low frequency noise.
Is there a problem to place a capacitor of about 1 to 10 μF on the SENSE pin?

Hi Yuto-san,

There will not be a problem placing that capacitor on the SENSE pin.
