Hi team,
It seems that TPS543620 doesn't support the phase margin and Gain margin at webench.
Are there anyway to activate those?

Hi Takahashi-san,
There is not a way to activate phase margin and gain margin in WEBENCH for the TPS543620. However, as long as the method given in the apps section of the datasheet for selecting the ramp setting is followed, the phase and gain margin should be sufficient for stability. WEBENCH follows this same method. I have given a link to the specific section below.

Alternatively the SIMPLIS model (linked below) can also be used to check the phase and gain margin.
