Abstract
A circuit for use in a power converter includes a control circuit coupled to detect whether an electrical energy source is coupled to an input of the power converter. A switch is coupled to the control circuit, and is coupled to transfer energy from the input of the power converter to an output of the power converter during a first operating mode. The control circuit is coupled to drive the switch in the first operating mode when the electrical energy source is coupled to the input of the power converter. The control circuit is coupled to drive the switch in a second operating mode when the electrical energy source is uncoupled from the input of the power converter to drive the switch to discharge a capacitance coupled between input terminals of the power converter to a threshold voltage in less than a maximum period of time.
