Patent attributes
Aspects of various embodiments of the present disclosure are directed to applications utilizing voltage regulation. In certain embodiments, an oscillator circuit is configured to generate an oscillating signal having a frequency specified by a frequency control signal. A switching power converter is configured to regulate a voltage at an output node according to a target value. The switching power converter enables a path that provides a current to the output node for cycles of the oscillating signal in which the output voltage is below (or above) a first threshold voltage. The switching power converter prevents the path from being enabled for cycles of the oscillating signal in which the output voltage is above (or below) a second threshold voltage. A control circuit adjusts the frequency control signal based on the number of cycles of the oscillating signal in which the path is presented from being enabled.
