TPS26750: Informations about suitable chip to drive a 36V lamp via USBC

Part Number: TPS26750

Tool/software:

Good afternoon, i contact you from an italian company involved in led lighting for horticulture. We are planning to implement USB-C port on our devices, but actually we are using a 36V input. We have seen that the last standard about usbc-pd epr, can reach up to 48V. Do you have any wuitable chip to be used as a broker able to withstand 36V? More specifically we are using a "dumb" 36V power supply, not a USBC PD device, and we would like to keep using that, but include the possibility to be driven by usbc sources (EPR or not). I'm sorry if i'm not very technical, but i'm trying to help my engineer who is struggling with this project.
Thanks for the help you could give us.

    Hello, 

    The TPS26750 would be the device to use if you want to take advantage of the new PD3.1 Extended Power Range. This is what you are referring to that increases the maximum voltage to 48V. With the new extended power range, 3 new voltage options were introduced, 28V, 36V, and 48V. The TPS26750 is able to negotiate these new voltages, and you can set the maximum to 36V. 

    One thing to note, if you do want to take advantage of this new extended power range, you will need to use a USB PD source capable of negotiating the new extended power range voltages. You will not be able to use a "dumb" 36V source.
