TPS54260-EP Buck Converter maximum input voltage range is 65V.
In our design, TPS54260-EP placed after TVS diode.
While performing lightning test , will get around 90V after TVS diode. These 90V is directly going to Buck Converter TPS54260-EP.
Please confirm TPS54260-EP will withstand 90V at 120uS , if not please provide some solution on this.
