TPS55340: TPS55340 load transient in the different output capacitor

Hi

I do the TPS55340 experiement in different output capacitor, but the output as follow:

I want to know why a bigger output capacitor have no different with small output capacitor in control overshoot in higher output current.

You can see in the small output current, the bigger output capacitor have a better performance to control the overshoot.

I tested the overshoot in the various output current, I can see the crossover frequency is higher in bigger output current.
