Abstract
A switching system and a power converter for use therewith are disclosed. A first switching device (20) selectively couples and uncouples a first terminal (26) of an inductor (24) to a predetermined signal line (22) in dependence upon a first control signal received along a control input (30). A second switching device (32) selectively couples and uncouples the first terminal (26) of the inductor (24) to ground in dependence upon a second control signal received along a control input (36). A switch controller (60) generates the first and second control signals based upon a pulsed signal generated by a pulsed signal source (46). The first control signal enables the first switching device (20) when both the pulsed signal is at a first logical level and the voltage at the control input (36) of the second switching device (32) is less than a predetermined threshold.
