Questions
How big is the TPS54202 PCB?
It measures 23.9 × 10.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TPS54202 use?
15 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 TPS54202 KiCad files?
From the lbernstone/TPS54202 repository on GitHub, at the commit this page was made from: the board is TPS54202.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the TPS54202 design in my own project?
Its repository states no licence, so its author keeps all rights: ask lbernstone before reusing the design.
