Minimum Switching Frequency (fS.QRmin) The minimum switching frequency occurs at the minimum input voltage and full-load condition, which should be higher than 20kHz to avoid audible noise. By increasing fS.QRmin, the transformer size can be reduced. However, this results in increased switching ...
But when the Logic input is made high, this high voltage should be a minimum of 1.25V (Diode Forward voltage) the IR LED conducts and so the photo-transistor is also turned on. This will short the collector and emitter and hence the Logic Output voltage will become zero. This way the ...
