LM5176-Q1: LM5176

Part Number: LM5176-Q1
Other Parts Discussed in Thread: LM5176, CSD17573Q5B, CSD18532Q5B

Hello,

I have designed a power management board based on LM5176 evaluation board circuit including same BOM, but after receiving the samples and test the board unfortunately it did not work as it should be it only work as buck mode and did not work in Boost mode.

after several trials to troubleshoot the issue it works only after replacing  Q7and Q8 (old part no."CSD17573Q5B" with new part no. "CSD18532Q5B") so all  the 5 mosfets have same part no.

but as in evaluation board they suggest to use  2 models ."CSD17573Q5B" and "CSD18532Q5B".

could you explain what is going on?
