Hi, support team
I'm evaluating LT8315 non-isolated circuit on page 21 Figure 9.
I want to measure the phase margin of this circuit.
However, I don't know how to measure it because it is not a general Buck.
How can I measure the phase margin using FRA on a real board?
Is it also possible to use LTspice for measurement?
That is similar to the standard evaluate board. The phase margin is >50 degrees.
You can measure the phase margin using FRA on a real board, but you need to use differential probes.
Thank you for your reply.As expected, we need to use a differential probe.I will try it.
