Abstract: In an embodiment, a voltage converter includes: a first transistor coupled between an internal node and a first node receiving a supply voltage; a second transistor coupled between the internal node and a second node receiving a reference voltage; an inductance coupled between the internal node and an output node; a first circuit controlling the first and second transistors; and a second circuit configured to detect, when the first and second transistors are in the off state, when the voltage of the internal node is equal to the voltage of the output node, to condition a switching to the on state of the first transistor.

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.
