At one point in the past I saw specs for the converters that included the switching rates
If you find that link again, I'd be interested. The patents didn't seem to state the switching rate, but they did give the RC values that controlled the switching, and I looked up the chart in the specs for the Unitrode 3846 chip to find out what rate those values corresponded to. I've forgotten the freq. I calculated (it may have been 10KHz, but it's very vague), and in any case, I can't be certain that the values listed in the patent were actually used in the production models of the converter.
