oh. Still hard to figure out exactly what your goal and problem are between "using the barrel jack side" and ATX supplies... If you already have 12v3a and that's what you want can't you just wire a normal 12v3a charger straight to the usb...? maybe this helps? https://www.pretzellogix.net/2016/11/14/a-review-of-four-swi... | ||

I have an ATX supply with 12v dc output leads. I have a usb-c powered device which can only consume 12v dc coming in on usb-c and needs to be signalled, or attached to a power source which matches the signals. I do not need a buck conversion. I need the supply side signalling suitable to act as a 12v usb-c output, to connect to the devices usb-c input. A pd trigger appears to be a chipset which acts as a device needing power and accepts voltage in on usb-c to put out, offering the client side signals to trigger 12v to be emitted. I want the other direction: the chipset and logic which would be inside a 12v power source emitting usb-c. It doesn't help that 12v was the voltage emitted from the final specification, it's optional. | ||
