Hello can you tell me if the minimum output capacitor value given on the quickstart is the value after MLCC derating or before?

Hi Genny,
You may find additional description that you should considerthe DC bias derating for MLCC.
Generally, Cout should selected by considering rippple, rms current and load transient.

Yes, I saw that, but I was still a bit confused. The value I enter - is it the "datasheet nominal value" or the derated value for my voltage from the curves on the datasheet?
Hi Genny,
the value in the quickstart calculator is the effective value of the capacitor. So you need to have in your hardware a higher capacitor with considering the DC Bias derating.
In the quickstart calculator you have to enter the derated value.
