DIY USB C PD power supply

IgorM

I'm looking for a board that allows me to convert a power supply to provide USB PD power similar to what this dell adapter does https://www.dell.com/en-us/shop/dell-adapter-74mm-barrel-to-usb-c/apd/470-acfh/pc-accessories

But on the web I mostly find this kinds of boards designed for consumer devices and not provider: 51tBYbk-rBL._AC_SL1000_-e1580121468911.jpg

Where can I find this types of provider boards?

This is a TI reference design meant to show engineers how to design their own USB PD DFP supply, but it should do the busines https://www.ti.com/tool/PMP40001. It's probably a bit bigger than you would like, but that's kind of the reality here if you want the full 100w that USB PD can deliver. As soon as I wrote that last sentence, I checked the module and it tops out at 60W, but still. It's a non trivial amount of power to deliver. I'll see if I can find  smaller DFP module.

Check your favorite electronics vendor like Digikey or Newark. Spoiler alert: it won't be cheap because it's a reference design.
