Power Delivery Operating Waveform
When connecting this board (Source side) and power receiving device (Sink side) using
Type-C dedicated cable, the Source side detects the Sink side and outputs 5V voltage to the
VBUS pin. After outputting 5V voltage on the Source side, it communicates with the Type-C
controller IC in the dedicated cable to acquire cable information.
After communicating with the cable on the Source side, the Source side transmits its own
power profile information to the Sink side. (Source Capability)
The Sink side requests an appropriate voltage from the power profile to the Source side.
(Request)
In response to the Sink side voltage request, if the Source side is able to deal with it, notifies
the Sink side that it acknowledged. (Accept)
The Source side outputs the requested voltage to the VBUS pin.
After outputting the required voltage, the Source side notifies the Sink side that the
requested voltage has been output. (PS_RDY)
After confirming the requested voltage, the Sink side turns on the FET switch on the VBUS
line.

<Caution>
It can’t be used for mass production because the power efficiency is bad with 75％
When a photo coupler short-circuited, safety has not been secured because there are no
protection circuits.
It’s for evaluation, so it doesn’t correspond to the safe standard by which it’s for UL, PSE.
Please use as a demonstration kit for USB-PD evaluation.
