DigiKey has seven pages, in stock, some with prices in the single digits.
Can't you do your own searches?

If finding/specifying a power supply is in your 'too hard' box,
perhaps it is time to consider a change of profession ?
{ Digikey popped out 29 suggestions in a few mouse clicks.... }

To be quite honest, your attitude and skills are not suited to this endeavour. I
suggest you find an easier hobby or somewhere else to whine.
I guess this sort of thing is a product of a consumer generation that just
expects to buy ready made solutions, made cheaply in China. It is kinda sad that
people don't seem to have any idea about making things any more.

Ooooh aren't you a clever boy? Yet still no real products. You spend
300-400$ for a SBC, then what? You get a cheap kludge, or some off-
brand mystery part to power it?
Clever! Clever!
BTW, "battery" doesn't mean "car".

Again. Why supply LCDs if you don't supply the backlight controller?
The same companies supply touch controllers.
Why not a backlight controller? Makes no sense. SBCs aren't designed
for "tinkerers".
You guys are just making excuses for a situation that's absurd.

Oh yes, 38V to 45V input. Now I just need a battery powered 40V
supply! Brilliant!
Let me guess: none of these products are stocked by any of the big
distributors, or if they are, they're 500$ each.

Find where the EEM (Electronic Engineering Master) catalog is, online
or a paper copy (if they still do that) in a decent library's reference
section, and look in the DC Power Supplies section.
The buzzword is "DC-DC converter".
Last I checked, Jameco had some interesting looking potted modules
in the 10-25 watt range.
Don't expect cheap, except maybe telcom surplus with 48 volt inputs.
