    Abstract: An embodiment voltage converter includes a first transistor and a second transistor coupled in series, and a first circuit configured to control the first and second transistors. The control terminal of the second transistor is coupled to a first output of the first circuit by a second circuit configured to delay the control signals supplied at the first output by a first duration. The control terminal of the first transistor is coupled to a second output of the first circuit by a circuit configured to delay the control signals supplied at the second output, for a second period of each operating cycle, by a duration equal to twice the first duration and, during a second period of each operating cycle, by a duration equal to the first duration.

    Abstract: A method includes switching a switching circuit of the switched-mode power supply in a synchronous mode by turning on and off switches of the switching circuit in synchrony with a clock signal, wherein the switching circuit is coupled to an inductive element, and wherein the synchronous mode comprises a charging phase and a discharging phase; switching the switching circuit in an asynchronous mode by turning on and off switches of the switching circuit without being synchronized with the clock signal, wherein the asynchronous mode comprises a charging phase and a discharging phase; charging the inductive element during the charging phase of the synchronous mode; discharging the inductive element during the discharging phase of the synchronous mode; charging the inductive element during the charging phase of the asynchronous mode; and discharging the inductive element during the discharging phase of the asynchronous mode.

    Abstract: In an embodiment, a voltage converter includes: a first transistor coupled between a first rail configured to receive a supply voltage and a first node; and an inductance coupled between the first node and a second node configured to deliver an output voltage, wherein, at each operating cycle of the converter, the first transistor is maintained in the on state for a first time period proportional to the inverse of a voltage difference between the supply voltage and the output voltage.
