Could you please provide the information about dv/dt of the VDD of UCC21551-Q1 and UCC21331-Q1?
Hi Chen,
Similar to UCC2152x and UCC21222x families the recommended dv/dt is 5V/us as mentioned in the FAQ you linked to this thread.

Hi Andy:
According to your FAE, the value of dv/dt about UCC21551-Q1 is 0.5V/ns,which is greatly improved based on UCC21530-Q1. So could you please double check this information because wo got inconsistent value?
thanks!

Hi Chengdp,
I have confirmed with our design team the 0.5V/ns is correct. That will be the consistent value we'll go forward for UCC2155x product family.
