My customer is using TPS25831-Q1 for their design.
They have a question about current limit accuracy.
They are adopting “Buck average current limit”.
According to the datasheet, Rsns=15mohms, Rset=300ohms and Rlimit=11.8Kohms are recommended for ILIMIT=3.3A.
If all Rsns, Rset and Rlimit are very accurate (no error at all), as a rule of thumb, how much could the ILIMIT vary under all over PVT variations?
