Abstract
A circuit and method are provided for recuperating energy and decreasing driver power consumption in a switching converter. An inductor is directly connected between a gate driver and a gate electrode of a switch. A first burst pulse signal is generated, wherein energy from a power source is stored in the inductor and transferred to a parasitic capacitance of the switch. A driving pulse signal is subsequently generated to the gate electrode of the switch, wherein the gate voltage is equal to the supply voltage and no balancing current flows through the inductor. After the driving pulse signal is terminated a second burst pulse signal is generated, wherein energy is accumulated in the inductive element and returned to the power source. The energy provided from the power source during the first burst pulse signal is equal to the energy returned to the power source during the second burst pulse signal.
