Hi team,
My customer is using the TPS7A4901 now and is broken. The schematic and layout are below. We test the pin 8 and pin 1 waveforms. But the it should have over voltage condition. Could you please help check it? Thanks.

Hi David,
I have asked the ripple from the customer . But the max voltage will not reach the datasheet maximum. Can it be broken?Thanks.
Hi David,
The customer tested the board again, no werid phenomenon happen. Do we think the failures can only be caused by the over voltage or output voltage higher than input voltage. Thanks.
