Abstract
Driver circuitry includes power converter circuitry, switching control circuitry, and switching frequency limiting circuitry. The power converter circuitry is configured to receive and selectively provide an input signal to one or more power conversion components via a power converter switching element to produce a regulated output signal. The switching control circuitry is coupled to the power converter switching element and configured to provide a switching control signal for controlling the power converter switching element based on a frequency limited switching trigger signal. The switching frequency limiting circuitry is coupled to the power converter circuitry and the switching control circuitry and configured to receive a switching indicator signal from the power converter circuitry and provide the frequency limited switching trigger signal based on the switching indicator signal and the switching control signal such that the frequency limited switching trigger signal limits the frequency of the switching control signal.
