Uses my personal favourite switching controller, good for up to 2A.. Changing the FB resistors will change the ouput voltage though efficiency may suffer. Input coltage is designed to be 9V to 25V DC

My licence fee will be a donation to a charity I'll specify and it's won't be much for a simple project like this.
The Gerbers are laid out in the correct format for JLCPCB, you can simply upload the ZIP file to them and order the boards.

Questions
How big is the TPS54202SwitchingPSU PCB?
It measures 33 × 10 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TPS54202SwitchingPSU use?
10 parts, built around the TPS54202DDC. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the TPS54202SwitchingPSU KiCad files?
From the phildimond/TPS54202SwitchingPSU repository on GitHub, at the commit this page was made from: the board is TPS54202SwitchingPSU.kicad_pcb and its schematic TPS54202SwitchingPSU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TPS54202SwitchingPSU design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
