IPC: H02M3/155

Abstract: The converter uses the energy stored in the output filter of a step-down (or buck) converter and in the inductor of a step up/down (or buck-boost) converter to supply a second output of opposite sign. In particular, the converter has a first input receiving an input voltage; a first output supplying a first output voltage of a first sign; a second output supplying a second output voltage of opposite sign; a controlled switch connected between the first input and a first intermediate node; an inductor connected between the first intermediate node and the first output; a diode connected between the first intermediate node and a second intermediate node; and a dual voltage generating circuit connected between the second intermediate node and the second output.

IPC: H02M3/155

Abstract: An SMPS converter with an inductor connected in series to the standard inductor present in the output filter to form an inductive divider supplying an intermediate voltage having an amplitude greater than the output voltage. The intermediate voltage is supplied to a capacitor that stores the voltage during the conduction phase of the integrated circuit that forms the switch of the converter and transfers the voltage during opening of the integrated circuit to a capacitor connected between the output and the supply input of the integrated circuit.
