Hello,
I measured on several different designs based on LT8638S a transient on output few ms after startup in no/light load conditions. During investigations, I noticed a transient on Vcomp, which seems to occur when SS reach around 1.7V.
The problem is not visible in LTspice.
Where does it come from? Is there a way to avoid such transient or is it intrinsic to the IC?
Here is my schematic
And here are the measurements (Vout in yellow, Vcomp in green)
Tnx
Dominique
