Embodiment Construction

[0050] In the ensuing description, various specific details are shown in order to provide a thorough understanding of the embodiments. Embodiments may be obtained without one or more of the specific details, or using other methods, components, materials, etc. In other instances, known structures, materials, or operations are not shown or described in detail so as not to obscure aspects of the embodiments.

[0051] Within the framework of this specification, references to "an embodiment" or "one embodiment" are intended to indicate that a particular configuration, structure or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, phrases such as "in an embodiment" or "in one embodiment" that may appear in various places in this specification do not necessarily refer to the same embodiment. Furthermore, particular configurations, structures or characteristics may be combined in any suitable manner in one or more embodiments.

Abstract

The application relates to stacked buck converters. A converter includes two switching stages coupled in series between positive and negative input terminals. A control circuit is configured for driving the switching stages based on an output voltage of the converter. A first switching stage includes two switches coupled in series between a positive input terminal and a first node. A capacitor andan inductor are coupled in series between the two switches and a positive output terminal. A third switch is coupled between a node between the capacitor and the inductor and the negative input terminal. A second capacitor is coupled between the first node and the negative input terminal. A second switching stage includes a second node coupled to the first node. Two additional electronic switchesare coupled in series between the second node and the negative input terminal. A second inductor is coupled between the two additional switches and the positive output terminal.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Italian Application No. 102018000010781 filed December 4, 2018, which application is hereby incorporated by reference. technical field [0003] Embodiments of the invention relate to electronic converters. Background technique [0004] Buck non-isolated voltage converters are widely used in the field of power management. Ease of use, simplicity, and good versatility over various conditions of input and output voltages make the buck topology one of the most widely used topologies for this type of conversion. [0005] figure 1 A circuit diagram of a typical buck converter 1 is shown. [0006] In particular, the buck converter 1 includes: for receiving the voltage V in The two input terminals 10a and 10b and for providing (for example, regulated) voltage V OUT of the two output terminals 12a and 12b, where the output voltage is equal to or lower than the input voltage V in . ...
