From the project

100W USB C PD Lithium Ion charging PCB based on the TPS25750D and BQ25713

This PCB is spec'd for 20V 5A USB C PD charging of a 1S configuration of Lithium Ion cells, it is suitable for dropping into a variety of battery powered projects that may be a bit more power hungry or where faster charging may be desired. Within this repository you can find everything to build this PCB, as well as source design files for it should you need to repurpose it for a different form factor or design.
