Question
At the L6562A: Is there any hidden "minimum" frequency implmented? Some sort of watchdog pulling the gate high even if no trigger is coming at the ZCD?
I use this IC as replacement of a similar IC. In the application I use the ZCD for a constant off-time circuit and also to disable the IC by pulling the ZCD high. This seems to be not working with this IC, as there are still output pulses generated.
