Abstract: An electronic circuit is for the gradual start-up of electric loads, particularly halogen lamps. The circuit may include a power device having an output terminal connected to the electric load and having at least one control terminal receiving a predetermined driving current value. The circuit may further include a comparator having a first input terminal coupled to the power device output and a second input terminal kept at a reference potential. The comparator output may be connected to a controlled switch inserted upstream of the control terminal to control the opening of the switch and adjust the start-up phase of the power device according to the value of the reference potential.

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.

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.
