Please help to support this issue.
For some problems encountered in the use of TPS2372-3, please help to answer, when using EVK: TPS2372-3EVM-757 to set its Jumper to Class 4, its LED indicator shows Class 7 / 8, but this IC does not support Class7/8 powered, what is the problem? Continuing to supply power in this case, is the PSE powered in Class 4 or Class 7/8?
