There is a reference design PMP6730. We can share the design but there is no board for purchase.
There is a TMDSEVM6657 EVM that has UCD9222 and UCD7242. But it includes DSP and FPGA on the board.
If your purpose is to learn/test PMBus operation, you can purchase a UCD9224 EVM.
Yes. TMDSEVM6657 has UCD9222 on the board. But it is a bit expensive because it also has FPGA and DSP on the board.
You will be able to test most commands using UCD9224 EVM, which is cheaper. But some commands are specific for UCD9222 (VID related, see PMBus reference document).
