1 microsecond places a genuine upper limit to the frequency of the converter. 100 khz is likely the maximum practical frequency for such a converter when this delay is incorporated.

ON THE METHOD OF REDUCING THE OCCURRENCE OF CONCURRENTLY SWITCHED-ON MOSFETs
How long must one wait after turning off one MOSFET before turning on another such that they are never on at the same time? I'm inclined to think a whole microsecond (1 µs) to be on the safe side. That's is enough leeway so that any buffers, inverters, drivers, gate delay, gate capacitance should still fall within that timeframe.
