Questions
How big is the TPS54331D BuckConverter PCB?
It measures 37.1 × 25 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TPS54331D BuckConverter use?
20 parts, built around the TPS54331D and B340. 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 TPS54331D BuckConverter KiCad files?
From the VANTA82/PCB-Design-Portfolio repository on GitHub, at the commit this page was made from: the board is TPS54331D_BuckConverter.kicad_pcb and its schematic TPS54331D_BuckConverter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TPS54331D BuckConverter design in my own project?
Its repository states no licence, so its author keeps all rights: ask VANTA82 before reusing the design.
