  • Voltage converter and method
    Patent number: 11967900
    Abstract: An embodiment voltage converter includes a first transistor connected between a first node of the converter and a second node configured to receive a power supply voltage, a second transistor connected between the first node and a third node configured to receive a reference potential, a first circuit configured to control the first and second transistors, and a comparator including first and second inputs. The first input is configured to receive, during a first phase, a first voltage ramp and, during a second phase, a set point voltage. The second input is configured to receive, during the first phase, the set point voltage and, during the second phase, a second voltage ramp.
    Type: Grant
