LT8652S SW pin absolute maximum rating with overshoot/ringing

Question

Hello. 
 Please could you let me know what the absolute maximum rating is for the LT8652S SW pin (SW1, SW2)? How much (if any) overshoot is tolerable on this pin? 
 For example, win Vin = 12V, the datasheet shows approximately 1V of overshoot on the switch node (assuming this is not an oscilloscope probe artefact). So if I operate the LT8652S at 18V I might expect the SW node to reach 19V. Would this be acceptable? 
 
 Thanks for the help.

Hi daedalus, 
 The SW pins can handle spikes over 18V. But for best life time, it is advisable to follow the layout example in the datasheet and keep the spike at less than or equal to 18V.
