1. A method comprising:

  • detecting an output voltage of a single-phase voltage regulator;

    sensing an inductor current corresponding to a saturating output inductor of the single-phase voltage regulator;

    generating a switching frequency signal based on the inductor current; and

    controlling the voltage regulator based on the output voltage and the switching frequency signal, wherein the switching frequency signal sets a first switching frequency if the inductor current is below a saturation current threshold and a second switching frequency if the inductor current is above the saturation current threshold, and wherein the first switching frequency is less than the second switching frequency.
