Abstract: A driving circuit comprises a switch mode power converter circuit to convert a supply voltage (e.g. rectified mains), including an energy storage component and a main control switch. The energy storage component discharges to provide a regulated DC current to an output load upon the switching of the main control switch. A time-varying offset is used to modulate the regulated current hereby controlling the voltage across the energy storage component. In this way, the voltage across the energy storage component is maintained above the supply voltage with a safety margin, and this is used to prevent input current spikes and hence prevent an efficiency reduction of the driver circuit.
