Part Number: LM5161
Under the "Absolute Maximum Ratings", section 6.1 of LM5161 datasheet, the minimum "SW to AGND" value is -1.5. In this particular design, the customer measured a transient that peaks at -1.8V. Is this something with which we should be concerned? The datasheet is not specific whether this "SW to AGND" rating is continuous or transient only.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Not sure what the question is Chauncy?
Can you re phrase please?
In reply to Keven Guan:
What I mean is the setting of 'Bw' on the oscilloscope as below red rectangle shows.
When measuring high frequency ringing, its best to set the scope on the highest BW setting. Suggest at least 100MHz. This will capture most of the waveform with minimal filtering.
Hope this helps,
