Hi All,

I simulated TPS53513 with webench, but there was no phase margin result.
Is it possible to simulate the phase margin?

Hi Ishiwata-san,

There is no way to activate phase margin and gain margin in WEBENCH for the TPS53513. 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.
