DP100 PD-Power Supply 100Watt [0-30.00V / 0-5.000A) [∼50$]
soopahfly:
I'd love to give this mod a go, is there anywhere I can buy the bits from?
Thanks!

Maybe someone can answer this: The DP100 can be supplied with up to 30V. But the PD trigger CH224K datasheet states 24V absolute maximum input voltage. Is the voltage seen by the CH224 limited somehow?
2nd question: I do not have a DP100 right now, but if I buy one I would like to upgrade the DP trigger to 3.1. Is there enough space left for an extra 0.8mm PCB (about 6x6mm) with a PD3.1 trigger. It cannot be mounted within the space of the ESSOP10 package for sure - but maybe somehow above the desoldered CH224 with wires?
Think about the HUSB238 from Hynetek, available at LCSC: https://www.hynetek.com/uploadfiles/site/219/news/24322c00-2276-4d74-98db-c74432318210.pdf#page30
Or a ready made PD Trigger from Aliexpress.
BTW: I know there are many ready made external trigger cables available.

You are not using the PD trigger for voltages above 20v (PD3.0/5A)
It will accept both these modern chargeprotocols, like PD (PD3.0 and below) & QC Quickcharge but also just crude DC input.
When I use it for fx 24v, and to run these double digits optical-wattage lazing rigs below, that needs 24v, I trigger PD3.1 from my power-bank (28v/5a) that I trigger outside, and then I dial it down with the DP100 to 24v.
DP100 takes the 28v as a crude DC-input.

I assume he is concerned about if the CH224 sees the bus voltage even if it was not triggered by itself. If no one knows it I can measure it soon.

Exactly. As far as I know the external „up to 30V“ is also plugged into the USB-C via adapter cable - correct? So if the CH224 is in parallel to the USB-C port it will be driven out of spec.
