I assume there’s not a single chip solution to the PD protocol? The plan was that I’d have a boost/buck converter at the input to convert any voltage to 5V and connect it either directly or through a controller/manager chip and maybe have multiple input jack sizes to accomodate as many types of chargers as possible. Or if I decide I want to charge with more power than have the controller charge at 20V or something.
Sorry if I’m saying nonsense, I have never designed a USB-C circuit, let alone with PD functionality.
