65W USB PD3.0 (Power Delivery) solution
« on: July 03, 2020, 10:46:59 pm »
Hi guys,

I am working on a new product. The product has a need for USB PD3.0 power delivery on a USB c port. I have no prior experience on implementing USB Power Delivery and wanted to see if anybody has some good ideas while I am further studying the topic myself!

Essentially the solution I am still deciding on is a USB PD3.0 power delivery solution. Essentially our device should act as some sort of USB hub in this regard and must deliver a minimum of 65W to one upstream USB-C port, confirm USB PD3.0. Our device should act as an USB PD source only, no sink capability needed.

Our device will have an DC power rail available to feed the circuitry. Something like a pre-qualified 20V-5A wall brick. These values are not set yet, for example it might make sense to have a higher voltage brick so the PD3.0 implementation can be done with a buck topology only. But I would need to see if we can get that to be compliant. So, for now I am favoring a more flexible buck/boost topology.

So basically I am searching for parts/topologies to make the PD3.0 work. A USB PD3.0 Controller who does all the PD negotions over the cc lines and a suitable buck/boost solution which voltage/current output is preferably being controlled by the PD controller directly, although we also have an application processor available in the system. MCU’s with native PD3.0 support might also be considered as nothing is set yet in this project, I see ST has some although they seem to be not yet available.

As a side note, the data-path has some very specific requirements for this project and this part is already solved. I am only looking to solve the PD3.0 part at this point.

I strongly suggest looking at Texas Instruments’ website. They have a massive catalog of reference designs, a large part of which are power related. They’ve got tons of USB power designs, including USB-C and USB PD.
