摘要： A control circuit of the power converter according to the present invention comprises a feedback circuit, an output circuit and an adaptive clamping circuit. The feedback circuit generates a feedback signal in accordance with an output of the power converter. The output circuit generates a switching signal in accordance with the feedback signal for regulating the output of the power converter. The adaptive clamping circuit limits the level of the feedback signal under a first level for a first load condition. The feedback circuit determines a slew rate of the feedback signal for increasing the level of the feedback signal from the first level to a second level. The adaptive clamping circuit is disabled and the level of the feedback signal can be increased to the second level for a second load condition.

摘要： A method and an apparatus for detecting a CCM operation of a magnetic device are developed. The method generates a current signal in accordance with a switching current of the magnetic device and generates a first current signal and a second current signal by sampling the current signal. A mode signal is further generated according to the first current signal and the second current signal. The mode signal indicates the magnetic device is operated in CCM or DCM. The apparatus comprises a first sample circuit, a second sample circuit, and an arbiter. The first sample circuit samples the current signal to generate the first current signal. The second sample circuit samples the current signal to generate the second current signal. The arbiter generates the mode signal according to the first current signal and the second current signal for indicating the magnetic device is operated in CCM or DCM.
