Field: nan (nan)
Classification: CPC nan | IPC H

Claim 20:
21. A voltage converter comprising:
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 multiplexer receiving as input a first voltage ramp, a second voltage ramp, and a set point voltage;
a comparator comprising first and second inputs, wherein the first input is configured to receive, during a first phase, the first voltage ramp from the multiplexer and, during a second phase, the set point voltage from the multiplexer, and wherein the second input is configured to receive, during the first phase, the set point voltage from the multiplexer and, during the second phase, the second voltage ramp from the multiplexer; and
a state machine coupled to a control terminal of the first transistor and a control terminal of the second transistor, wherein the state machine is configured to receive input from the comparator and to provide a control signal to the multiplexer.
