Abstract
A control voltage for a synchronous rectifying transistor is generated with the desired anticipation time. The anticipation time is continuously controlled with a closed-loop technique by comparing it with the duration of a reference pulse. The resulting error signal is processed and provides the necessary correction to the MOSFET gate signal to equalize the actual anticipation time to the duration of the reference pulse.
