  • SELECTIVE STOPBAND AVOIDANCE IN SWITCHING CONVERTER CONTROLLER
    Publication number: 20240022169
    Abstract: A switching converter controller includes: a stopband controller having a stopband controller input and a stopband controller output, the stopband controller is configured to provide stopband information at the stopband controller output responsive to a reference signal; a pulse-frequency modulation (PFM) controller having a first PFM controller input, a second PFM controller input and a PFM controller output, the first PFM controller input configured to receive a feedback error signal, the second PFM controller input coupled to the stopband controller output, and the PFM controller configured to selectively adjust a clock signal at the PFM controller output based on the feedback error signal and the stopband information; and a driver circuit having a driver circuit input coupled to the PFM controller output and configured to receive the clock signal, and having a driver circuit output adapted to be coupled to a power stage switch.
    Type: Application
