TPS40057: About the Absolute Maximum Ratings for negative voltage at SWpin.

Hi team.

I'd like to know about the Absolute Maximum Ratings for negative voltage at SWpin.

My customer has the negative voltage at SWpin of -1.6V for 120nsec.

Is this a problem?

Could you see the following waveform?

Voltage : 500mV/div

Time : 50ns/div

I'd like to confirm if we can make time to longer ,when the negative voltage is relax from the data sheet.

Sincerely.

Kengo.
