Hello TI,
We have designed a board with multiple TLV62569 to generate 5V to required rail . Each rail has trimp pot on feedback path. Boards are working fine, but over a period of time some boards SW PIN is getting short to GND unlikely and also in some of boards FB pin became insensitive to fedback network voltage, FB pin is not isolated from die, it shows diode continuity. we are debugging the issue.
Any help on this debug ? let us know if you need more data for analysis.
Rough Sketch of board:
Thanks,
Shivaji M
