Hmm... Is it installed the right way?
On the new boards we've replaced the MP2359 with the pin and function compatible RT8259GE - great that's OOS at Digikey. Same with XRP7659 and AOZ1282CI-2.

Good luck sourcing semiconductor parts in this economy!

We *think* it's installed the correct way. There's no dot or line on the chips we got, just text IF8BH. Googling that brings up a part, even related parts, but no datasheets. We oriented it with the "I" on the dot side, and the "H" on the far side, since that seems to be convention. There's another candidate for the problem, though. I have a 330uf cap next to the inductor where I was apparently supposed to order a 100uf. Might explain the small arcing if I connect the power jumpers after the PS is already on. Found and ordered new chips and caps, so we shall see. Shipping hurts, but qtys of 10 or less are easier to find.

Yesterday I wrote a bit of text in the new JLC guide on how to order any "missing" parts. Looks like I should include a line saying not to do it when you're tired.

Is there anywhere a bunch of known-good part substitutions are listed? Would like to include that in the guide.
