The TPS53626 selected for our new project 3028; In the actual debugging, it was found that the VREF of the chip was about 1.4V after the motherboard was started, and the problem was still the same after testing 3 motherboards and replacing multiple chips. Please assist in the analysis, after disconnecting all links around the vref, it is still 1.4V, the standard should be 1.7V, and the attached part is the schematic diagram of this part; We hope you will reply soon.
