This disclosure relates generally to radio frequency (RF) switching converters and RF amplification devices that use RF switching converters. For example, an RF switching converter may include a switching circuit that receives a power source voltage and a switching controller that receives a target average frequency value identifying a target average frequency. The switching circuit is switchable so as to generate a pulsed output voltage from the power source voltage. The switching controller switches the switching circuit such that the pulsed output voltage has an average pulse frequency. The switching controller also detects that the average pulse frequency of the pulsed output voltage during a time period differs from the target average frequency, and reduces a difference between the average pulse frequency and the target average frequency. In this manner, the effects of manufacturing variations and operational variations on the average pulse frequency can be eliminated, or at least diminished.
