Hello guys,
i am working on a project to control vast amounts of leds. Due to the long distances and current requirements involved, i plan to distribute 48v and step down to 12v locally.
Originally, i was going to use these
https://www.amazon.com/uxcell-Step-Down-Waterproof-Converter-Transformer/dp/B01ENGOA4S
one for each 5m of led strip. However, i would like to make the project modular... and easier to install so i found some connectors i can make a pcb to distribute power and make the project modular but for this to work i need to be able to put the converter on my own pcb so i can get rid of all the wiring...
I found these:

But i think in the quantity i need for the project, i can make my own for a better price. What is in the converter from uxcell? Is it just a control chip, diode, mosfet, inductor and capacitors? What determines the current output? I need a minimum of 80w @ 12v....
