UCD90120A: ucd90120a PMBUS operation and USB adapter hardware design

Is there a reference design for the TI USB/PMBUS dongle. I am adding this hardware and want to make sure I have all the hooks in place.

    The Digital Power Forum supports many products that make use of the USB-to-GPIO adapter but does not directly support the design for this adapter (or at least it hasn't been to my knowledge)

    The big issue would be the TUSB3210's firmware (and the instructions for loading) as the full schematic is included in the USB-to-GPIO User's Guide.

    You could try posting to the USB forum at:

    Or you might be better off purchasing the stand-alone USB-to-GPIO adapter to use with your hardware at:
