TPS53515: Repeated device failure

Part Number: TPS53515

Hi,

We have 5 TPS53515 on my board for several supply voltages.

We manufactured >100 boards until now.

We had two incident of failed TPS53515 device. The failure was on the same device that output a 1.2V and was designed for 5.6A.

In both failures the output was ~1.15 instead of 1.2. After debug we got to a conclusion that the device is the cause of the failure and not the device peripheral. and after replacement the board worked properly.

One Board failed after it was working for a year and the second board failed immediately after manufacturing.

We are concern that it might be a design or reliability problem and appreciate a design review (I can send the design by mail).

I review the threads of the TPS53515 and didn't see anything that can help with the problem.

Thanks

Yossi
