Abstract

In accordance with an embodiment, a method of operating a switched-mode power converter includes measuring an input voltage of the switched-mode power converter; determining an on-time of a switch of the switched-mode power converter; determining an off-time of the switch of the switched-mode power converter; and determining an output voltage of the switched-mode power converter based on the measured input voltage, the determined on-time and the determined off-time. The output voltage includes a voltage at a first node having a DC path to a load path of the switch.
