Abstract
Systems, methods and circuits for regulator minimum load control. In one particular case, a system is provided that includes a load control circuit and a switched load. The load control circuit includes a reference current, and a sense current representative of a load current. In addition, the load control circuit includes a comparator circuit that drives a control signal in response to a comparison between the reference current and the sense current. The switched load is electrically coupled to a load voltage signal to provide loading to the load voltage signal. The switched load is operable to switch between a first loading factor and a second loading factor in response to the control signal.
