The USB-C has been around for quite awhile, but there is still a lack of a miniature basic USB-C chargers for LiPo battery. I decided to make my own with as minimal footprint as possible, which resulted in being 13.5mm x 16mm. A well known MCP73831 is used as a battery charger in DFN package, to minimize the risk of thermal throttling. Today I have manually assembled the first prototype, which has survived a smoke test!
