From the project
A "Simpler" Charger
This is a two-port USB charger design based around the Texas Instruments TPS25858-Q1 controller. It's designed to be part of a larger project to build some charging infrastructure into a shelf, hence the terminal block connections rather than actual USB-C ports. Input power is intended to be 15V coming from a power brick and the intent is to have several of these providing something like 12 ports in total (so 6 completed boards).
