Tool/software: WEBENCH® Design Tools
I use webench to simulate the TPS54020's phase margin and gain margin on my application.
My input is 12V, and when output is 3.9V/4.29A or 1.8V/2.28A the webench runs normally, but when output is 2.4V/2.48A, webench says it cannot simulate.
It seems that webench is related with output voltage. If I change to 2.41V or 2.39V webench runs with a new parameter "coutx."
It happened this week, last week didn't happen.
Does server go wrong?
