Hello,
My customer design the power supply board using LM25118.
The LM25118 sometimes gets damaged during operation.(output voltage abnormality)
I have some questions about this device.
Q1.When the HS pin exceeds the rated voltage,is there damage to the HB pin?
I will attach the file(Switching waveform) to this post.

Q2.Regarding the HS pin pattern layout,what should I be careful about?
Best regards,
Seishin
