Powering usb-c device with power supply that doesn't support PD

trivettegiacomo · ‎2024-06-11

Hi, i'm trying to power an usb-c device that needs 5v 2A, with a power supply (5v 8A) that doesn't support power delivery. For doing that i tried to use the evaluation board EVAL-SCS002V1 connecting the power supply wires (+ and -) to the green connector and the usb-c one to the device to power on. The result is that only the board blu led is turning on that means "default USB current".

How can i negotiate for more current? What am i doing wrong?

Please help me 🙏.

Regards,

Giacomo
