  • Patent number: 11128218
    Abstract: An adaptive frequency adjusting system is provided. An error amplifier outputs an error amplified signal according to an output voltage of a power converter and a reference voltage. When a comparator determines that a voltage of a slope signal reaches a voltage of the error amplified signal within a maximum on-time of an upper bridge switch, the comparator outputs a reset signal. When the comparator determines that the voltage of the slope signal fails to reach the voltage of the error amplified signal and the maximum on-time ends, the comparator outputs the reset signal and instructs a clock generator to output a clock signal having a lower frequency. A driver circuit turns off the upper bridge switch and turns on a lower bridge switch according to the reset signal, and drives the upper bridge switch based on the clock signal having the lower frequency.
