Hi , i want to ask if there is any documentation reports of testing the respond of any Topswitch family power supply
to voltage input surges , how it affects the output voltage regulation ?

Hi,

We dont have any special document which reports the surge behavior and its effect on regulation. Most of the design examples available under TOP switch family section are tested for Differential and common mode surges. For reference, check DER-243 tested for 1.5kV DM and 3kV CM surge.
If you have any issues passing surge or looking for higher surge requirements, please let us know.
