Hello.
I confirmed the DC-DC Convertor(TPS65251RHA).
IC has been damaged while I am evaluating.
Three voltage stops outputting a phenomenon.
I think that the temperature limit has occurred.
However, it can not be confirmed fever device .
Do such abnormalities occur?
If there is a cause assumed, I will want you to teach.
Please refer attached waveforms.
It becomes the circuit diagram which I am evaluating.
I want an opinion, if there is a point feeling uneasy.
Regards,
okamoto
