In Design Example Report 287, entitled T8 Tube Lamp Driver, the input specification is 180 VAC to 265 VAC at 60 Hz.
If the circuit is plugged into a fluorescent lamp fixture, the circuit will be connected to the fluorescent lamp ballast. For instant start ballasts, the initial voltage is 1000 VAC at 60 kHz (<- note killo Hertz). The voltage will eventually drop to 120 VAC, but the frequency is still 60 kHz.
How does the circuit survive the hit from the ballast?
Did you intend to remove the ballast?
