Abstract
Methods and systems may involve detecting an output voltage of a voltage regulator and sensing an inductor current corresponding to a saturating output inductor of the voltage regulator. A switching frequency signal can be generated based on the inductor current, wherein the voltage regulator may be controlled based on the output voltage and the switching frequency signal. In one example, the switching frequency signal sets a first switching frequency if the inductor current is below a saturation current threshold, and sets a second switching frequency if the inductor current is above the saturation current threshold, wherein the second switching frequency is less than the first switching frequency.
