I have an eval. board from power intergration which uses TOP244 IC. The input is universal and output is 12V, 2.5A. The IC has a feature which protects it from input overvoltage. When I apply 1kV for more than 25msec, the power supply will shut itself down and thus reseting
12V on secondary side. I would like to achieve 50msec time before the power supply will shut itself down. Can anybody help me to achieve that?
