Abstract
A method, in some embodiments, comprises: receiving a feedback voltage signal generated by a switch-mode power supply; generating an error signal based on a difference between a switching frequency of the switch-mode power supply and a target frequency; and using the error signal to adjust a ripple amplitude of the feedback voltage signal to control said switching frequency in the switch-mode power supply.
