Hi Tadeusz,
That link works fine on my browser. I attached the quickstart calculator file.
I suspect the inductor is the root cause of the issue - maybe you can test with an inductor that is adeqautely rated.

Hello Dan,
Thank you for the schematic. There are a number of things that I have questions about.
What is the purpose of R212?
Why do you have a high-side snubber made up of R206 and C103?
What the values for C70 and C71?
What are the voltage ratings…
LM(2)5085_Quick_Start 5Vout 600kHz.xls Hello Nick,
I still think placing a parallel input bypass capacitance (<1uF) in addition to the input capacitance you have will help reduce the ringing.
Attached is a Quickstart tool which will provide guidance…

Hi Azofeifa,
Please see the attached quick-start excel sheet. There are few things that stand-out.
1. The input capacitor is small. Also in your design I don't see a small bypass capacitor at VIN.
2. The…
