    摘要: A power converter control method and apparatus is disclosed. An example control circuit includes a clock signal generator coupled to generate a clock signal to control switching of a power switch to be coupled to the control circuit. A feedback circuit is coupled to receive a feedback signal which is representative of an output of a power converter during a duration of a feedback portion of an off time of the power switch. The feedback circuit is coupled to respond to the feedback signal to control the clock signal generator to regulate a ratio of the duration of the feedback portion of the off time of the power switch divided by a duration of a total power switch switching cycle period.

    摘要: A power converter is disclosed. An example power converter includes an energy transfer element coupled between a power converter input and a power converter output. A power switch is coupled to the energy transfer element. A control circuit is coupled to receive a feedback signal representative of the power converter output during a feedback portion of an off time of the power switch. The control circuit is coupled to generate an output signal in response to the feedback signal. The output signal is coupled to be received by the power switch to control switching of the power switch to control a fraction of the feedback portion of the off time of the power switch that the feedback signal is above a threshold and another fraction of the feedback portion of the off time of the power switch that the feedback signal is below the threshold.
