    ARGH! Of course it's only now that I notice Webench generated a layout specifically for that schematic.

    I couldn't find any mention of copper thickness in the datasheet. No mention in the Evaluation Board for the TPS56637, but it does have a much nicer layout with A LOT MORE cooling holes and a wider area.

    I must have read about the copper thickness in the datasheet for another TPS. I just can't remember which cause I looked at so many.


    EDIT: No mention of copper in their Quick Reference Guide:

    My Creality Ender 3 S1 Plus is a giant paperweight that can't even be used as a boat anchor, cause I'd be fined for polluting our waterways with electronic devices.

    Not as dumb as yesterday, but stupider than tomorrow!
