Abstract

Disclosed is an active virtual loading applicable to the dc-to-dc conversion circuit wherein the dc-to-dc conversion circuit has an output terminal to provide an output voltage to a load, and a discrimination circuit and a pull-down circuit. The pull-down circuit is coupled with the output terminal of the dc-to-dc converter while the discrimination circuit is coupled to the pull-down circuit and pre-set a first designated voltage to detect the output voltage, and when the output voltage exceeds over the first designated voltage, output a first enable signal to drive the pull-down circuit so as to further lower the output voltage.
