LM5069: Surge test fault

Part Number: LM5069

Tool/software:

Hi Sir,

we found, test the DC input differential 1kv would trigger the LM5069-2 current limit and cause the machine to reboot.

change the R65 and R116 current sense resistor to 0 ohm to bypass this function, and the surge test will pass without rebooting.

may we know is there somewhere, we can modify to resolve this issue? thanks for you help and learn from you.
