Abstract
Disclosed are devices, apparatus, circuitry, components, mechanisms, modules, units, systems, and processes for controlling the switching frequency of a voltage regulator. Frequency monitoring and adjustment circuitry is coupled to sense a switching frequency of a power switch coupled to an output filter of the voltage regulator. The frequency monitoring and adjustment circuitry is configured to provide a frequency adjustment signal based on the sensed switching frequency. Power switch control circuitry is coupled to receive the frequency adjustment signal and is configured to control switching of the power switch based on the frequency adjustment signal.
