Abstract
A switch-mode DC converter configured to generate a converted voltage from an input voltage is provided. The switch-mode DC converter includes an inductor configured to store energy, and a switch coupled with the inductor at a switching node, wherein the switch is configurable to be turned on or off to control the discharging of the energy stored at the inductor to an output node of the converter, wherein the output node is configured to provide the converted voltage. The switch-mode DC converter also includes a circuit configured to control a timing of turning-off of the switch based on a voltage difference between the switch, wherein a measurement of the voltage difference is adjusted based on a voltage at the switching node.
