SLAU874 October 2022 TPA3223
This power mode is useful for certain applications where a system has one higher voltage used for PVDD and a second lower voltage that may be used for device pullups and other supplies (VDD, GVDD, and AVDD). The PVDD voltage can still be connected to J1 but jumpers J29 and J26 must be removed.
In the case of the TPA3223EVM, only 12V can be accepted as a non-5-V Supply and should be connected to pin 2 of J26 (12V).
