This is a work in progress. The prototype has not confirmed to work or function well yet. This module is designed with 48v VIN in mind, but can be used for any voltages lower, the inductor can be calculated for every scenario using https://www.schemalyzer.com/en/tools/buck-converter-calculator. Default operation frequency is 1.2Mhz but can be lowered to 600KHz for lower heat if space allows. This design uses a 4 layer PCB which is very affordable at JLCPCB as long as the inner layers are 0.5oz.
The module requires a 300uf~ bulk cap (perferrabily polymer) close to VIN on the main PCB. Ensure the area under the module is grounded to reduce EMI if possible.
Silkscreen is removed over certain sections of ground to improve heat transfer. A heatsink will be required on the backside depending on the required load. Use a non-conductive thermal tape to adhere the heatsink to the PCB as the VCC and GND vias are both exposed on the backside. If not in use, cover with kapton tape. I have to figure out how to get KiCad to only cover the VCC vias...

Questions
How big is the TPS922055-Module PCB?
It measures 36.8 × 22.3 mm and has 4 copper layers, 0.96 mm thick.
What parts does the TPS922055-Module use?
27 parts, built around the V8PM10-M3. 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 TPS922055-Module KiCad files?
From the GodessOfBun/TPS922055-Module repository on GitHub, at the commit this page was made from: the board is TPS922055 Module.kicad_pcb and its schematic TPS922055 Module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TPS922055-Module design in my own project?
Its repository states no licence, so its author keeps all rights: ask GodessOfBun before reusing the design.
