Overview
TP540xSAL is an open-source printed circuit board by cdntinker, from the cdntinker/TP540xEVM repository on GitHub. It is a 2-layer board of 36 × 25.7 mm with 19 parts on 9 nets, routed with 38 tracks and 12 vias.
It is built around the TPS5403D and DSK24. Its parts include 6 capacitors, 2 resistors, 2 connectors, 1 IC and 1 diode.

(This project started as a result of the truly awful EVM design from TI for these chips.)
This little circuit should work with either the TPS5403 or TPS5405 from Texas Instruments.
Both chips will accept up to 28V input.
The TPS5403 wants 4.5-28V & outputs 3v3 up to 1.7A.
The TPS5405 wants 6.5-28V & outputs 5v0 up to 2A.
The 3 boards
Standalone
Basically, a standalone voltage regulator board...
Module
A tiny little voltage regulator module (daughterboard)...
There is also a symbol/footprint/3D model set in KiCAD Customs for this module.
Carrier
Like Standalone, but using Module instead of parts on the board...

Questions
How big is the TP540xSAL PCB?
It measures 36 × 25.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TP540xSAL use?
19 parts, built around the TPS5403D and DSK24. 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 TP540xSAL KiCad files?
From the cdntinker/TP540xEVM repository on GitHub, at the commit this page was made from: the board is Standalone Hardware/TP540xSAL.kicad_pcb and its schematic Carrier Hardware/TP540xMCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TP540xSAL design in my own project?
Its repository states no licence, so its author keeps all rights: ask cdntinker before reusing the design.
