Assignee: STMICROELECTRONICS (ROUSSET) SAS
Field: nan (nan)
Classification: CPC nan | IPC H

Claim 0:
1. 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; and
a first circuit configured to control the first and second transistors, the first circuit comprising:
a selection circuit;
a comparator comprising first and second inputs, wherein the first input is configured to receive, during a first phase, a first voltage ramp from the selection circuit and, during a second phase, a set point voltage from the selection circuit, and wherein the second input is configured to receive, during the first phase, the set point voltage from the selection circuit and, during the second phase, a second voltage ramp from the selection circuit; 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 selection circuit.
