Dears:

I found that in TPS54678 datasheet , Vin=6V, PH voltage obvious over 7V. Please help check if it has risk in this situation ? Thanks.

Hi,

This is normal for any buck converter and is not an issue. On page 4 of the D/S, there are AC ratings for the PH node which show this.

And this is an old device. Would the TPS62867 meet your needs?

Thanks,

Chris
