Welcome
USB PD currently defines a maximum voltage of 20V, so the expected 45V cannot currently be achieved with USB PD without detours.
Correction: with the new specification for USBPD PD 3.1, a new voltage range is available in EPR mode (Extended Power Range). In contrast to SPR (Standard Power Range), EPR can now also negotiate 48V at 5A = 240W, provided a suitable USB PD source is available. ST is currently developing the appropriate hardware for sink and source.
