Abstract: A magnetic component for an electronic circuit includes first and second bobbins having respective core-receiving passageways. Each bobbin includes multiple slots with a winding insert in each slot. The winding inserts function as windings as well as guides for winding a coil of wire around the respective bobbins. The first and second bobbins are positioned on respective first and second legs of a magnetic core. The coils of wire are wound on the two bobbins in opposite directions such that the magnetic fluxes provided by the coils are in phase. The winding inserts have connection prongs that can be positioned in opposite direction such that the winding inserts of the first bobbin are connectable to a first printed circuit board and the winding inserts of the second bobbin are connectable to a second printed circuit board.

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.
