Abstract
In accordance with an embodiment, a switched-mode power converter includes a switch, a freewheeling diode coupled between an output terminal of the switch and a power supply input node, an inductor coupled between the output terminal of the switch and a power supply output node, and a passive network having a first terminal coupled to the output terminal of the switch, a second terminal coupled to a power supply output node, and a third terminal coupled to a reference terminal of the switch. A method includes measuring a first voltage at a fourth terminal of the passive network when the switch is on; measuring a second voltage at the fourth terminal of the passive network when the switch is off; and estimating an output voltage between the power supply output node and the reference terminal of the switch based on the first voltage and the second voltage.
