For those that want to use an ATX or other simular low voltage power supply this same company just released a new buck/boost version of the power supply module.
It outputs 0-32V and the input is 6-40V with a 5A max current.
This really opens the door for more compact and easier to build power supplies if you do not need the higher current and voltage abilities of the DPS5015
It is on sale during the introduction for $28.99 for 3 days, grab it while you can, they always do this when released and the price DOES go up after that.
Not that hard, the magenta curve shows the power loss in it. The maximum is about 10W in all the test I have done, the only significant exception is when I am very close to the current limit.
Here is the Design for the Acrylic case I made in case anyone wants to make one. It is cut out with a laser cutter from standard hardware store .08” acrylic sheet (“plexiglass”). Thicker acrylic would be stronger but costs a lot more and is much harder to find.
Proper acrylic glue will be stronger and look better but hot glue or super glue works just fine as well.
Ah right. So I’m guessing the external board connected to the DPS3012 is just because the control unit isn’t big enough to contain the beefier components?
Yes, that will work, you can find 48 power supplies as well. I got a 150W 48V power supply from ebay for about $14. Works great as long as you don’t need more then 150W (which would be very hard to do with a 12A limit in a flashlight).
