As a slight improvement, it might have been informative to include the specific physical location of the input capacitor described in your article (between the Vin pin of the converter IC/switch transistor and the anode of the switching diode).
Great article, Jeff -thanks!
There is some system bug which is preventing the "enlarge" of Figures 5 and 6 from appearing properly. Here are the direct links for those figures:

Great article, I would like to get a PDF copy of it, but the print link does not seem to work.
To add to comment of agk re: winding inductor with low parasitic C, another trick is to have the turns at the ends of the winding (near the connection terminals) spaced further apart compared to turns in the middle of the winding. This is an old trick used by ham-radio builders, and can result is a smaller inductor than would result from spacing all turns the same distance apart, but of course the parasitic C is a bit higher.
@PierreBTOL Loved this article! This other one was also useful in tips for common mode noise:
