Hello,

I see on the Framework website that the Framework 16 supports 48V/5A Charging, which is the current USB-C 3.1 EPR Max spec

I understand there are no chargers that support this yet, but looking at the schematics of the Framework 16 (https://github.com/FrameworkComputer/Framework-Laptop-16/blob/main/Mainboard/Mainboard\_Interfaces\_Schematic\_Framework\_Laptop\_16\_7040\_Series.pdf), I see that they are using a Infineon CCG8DF for PD communications, which supports the EPR up to 28V (https://www.infineon.com/dgdl/Infineon-EZ-PD\_TM\_CCG8\_USB\_Type-C\_port\_controller-DataSheet-v08\_00-EN.pdf)

So how can the laptop get more than 28V (140W)?

Thanks!
