My question is not about the speed of switching, but of the overall response time.

My center tapped push pull can handle 6 microsecond plus and 6 us minus pulses.  80kHz rep rate.

It's all easier, (not saturating), if you can do with slower, thus my question.

100kHz is the fastest most ordinary switcher cores run at, so there is easy shopping from 40kHz to 100kHz,
and you would not want to be below 40kHz so it is less audible.
