Tool/software: WEBENCH® Design Tools
Hello,
I'm using Webench designer to simulate a simple circuit using LMZ10503 part.
If I simulate my circuit with the SIM tab and show the bode plot, my design seems to be unstable (10° phase margin).
But if I go to the re-comp tab, my design seems more stable (38° phase margin) with the same value of components.
The two results are not the same with the same design, could someone explain this difference and what is the real phase margin of my design.
Thanks
Matthieu Baque
