UCD9222: Ask questions about circuit & PMBUS(UCD9222 and UCD7242).

Part Number: UCD9222
Other Parts Discussed in Thread: UCD7242


I use power control IC(UCD9222 and UCD7242).

For new projects, circuits such as C6657 EVM will be used.

Unlike the EVM circuit, the UCD 7242 input voltage would be 5V instead of 12V.

1. Should I change the circuit if I use 5V instead of 12V?

2. Should I change PMBUS program of UCD9222?

If you need to change it, what changes should I make?

please let me know your advice.

(Please refer to page 26 of C6657_EVM_SCH_16_00132_02.pdf)
