Hi all,
By mistake, I set the input of TPS78601 to 7.8V (which is beyond the maximum rating in the datasheet) for about 2 minutes.
After I change the input to 3V, the output and FB input are all zero, and 1.8V is the supposed output.
Since this is the new board, I can't know whether it is because of that the TPS78601 is damaged.
Acctually, I have 2 TPS78601 on the board. All of them get the same problem.
Is it possible that they are damaged?
Thanks
