Abstract
A synchronous converter that includes a power source, an inductor, an output terminal, and a control circuit. The control circuit may include: an electronic energizing switch that, when activated, delivers energy from the power source to the inductor; an electronic de-energizing switch that, when activated, delivers energy from the inductor to the output terminal, the electronic de-energizing switch including a body diode; and an electronic pull-down switch that, when activated, turns off the electronic de-energizing switch, redirects current flowing though the body diode of the electronic de-energizing switch, and removes charge from the body diode of the electronic de-energizing switch. The electronic energizing switch and the electronic de-energizing switch may never both be activated at the same time.
