<https://www.maximintegrated.com/en/products/power/linear-regulators/MAXESSENTIAL02EP.html> Datasheet: <https://datasheets.maximintegrated.com/en/ds/MAXESSENTIAL02EP.pdf> A set of _nine_ nice-looking eval boards for their new analog-focused, low quiescent power switching regulators, all for $49 in a nice plastic case and all. Dunno if I'm brave enough to use a Maxim part yet, but some of those look vaguely interesting.

Is Maxim now AD? If so, this set of SMPS eval boards is interesting

Analog owns both now. I hope they did a better job on switcher noise than Linear did. LTM8078 is ghastly. If you try the eval kit, maybe you could look at that.

We've revamped our standard photoreceiver packaging to use a machined-from-solid brass box with a flat brass lid, communicating via feedthrough caps and a U.FL F to bulkhead SMA cable. All the switchers go in another board under the brass box, with a black powder-coated steel or aluminum lid, with a black plastic shroud covering the feedthrus and supporting a bulkhead-mount power jack. The lid can be soldered down if desired, for really tough EMI situations. Once we have the new models up on the website, I'll post a link. Turns out that with modern laser cutting and 3D printing, the whole works is cheaper than the Hammond box we were using, besides being dramatically better electrically and much much more bling with all that gold(ish) and black. (Free-cutting brass looks more like gold than yellow sheet brass does.) Simon unofficially calls the new version of our QL01 nanowatt photoreceiver the DK02, for Donna Karan. ;) The new boxes are good for fast APDs, SPADs, and MPPCs/SiPMs. Check out SendCutSend for some very interesting capabilities.> > TPS54302 is pretty good.I've got that in my notes from your previous recommendation, but haven't tried it yet.

They keep adding capabilities--they now do laser-cut steel (12 different alloys iirc) up to 12 mm thick, for cheap. Even titanium. It seems to be just the sort of thing American manufacturing used to be unequalled at--apply capital and ingenuity to become the low-cost, high quality producer even in a high-wage country. They're pretty focused on laser cutting and surface coatings--anything out of the plane costs extra. Simon knows a lot more about them than I do, and is a huge fan. It reminds me a bit of designing with MSI logic chips BITD--with some time and creativity you can make some pretty neat things while staying within the cheap zone.

Maxim has been around for a long time. Maxim ate a lot of companies but there's always a bigger fish in the pond.

Maxim has been around for a long time. Maxim ate a lot of companies > but there's always a bigger fish in the pond.Maxim is infamous for teasing with datasheets and samples, but when it come to buying for production you are not getting any unless, I guess, you need millions so they can be bothered to actually make some
