Questions
What parts does the My power supply use?
68 parts, built around the TPS54560BDDA, CYPD3177-24LQXQ, B560C and DMP3013SFV. 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 My power supply KiCad files?
From the malcops/ps_pcb repository on GitHub, at the commit this page was made from: the board is my_power_supply.kicad_pcb and its schematic my_power_supply.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the My power supply design in my own project?
Its repository states no licence, so its author keeps all rights: ask malcops before reusing the design.
