Hi
The 1.8 V out from BUCK4 overshoots (to about 1.9 V) at power up.
One weird thing I see is that the switching node shows a bit weird behavior at 2 points. Please look at the graphs below to understand what I mean.
The graphs below show the output voltage in yellow and the switching node in red. The upper view is the oscilloscope capture and the lower view shows a zoomed in part of the capture.
Can you please explain the weird behavior on the switching node?
Can you please advise me on what to do/try/measure to get rid of the overshoot?
Regards, Jonas
