Hi,

What is the TPS54528DDA power down falling time? The output is 1.8V.

Thanks,

That is not a specified parameter. It depends on your output capacitance and load.

Hi John,

Do you any formular or easy way to estimate it?

Thanks,

It would just be the standard voltage discharge of the output capacitance thru whatever your load is.
