Abstract
The present invention provides a controller to control an output current by controlling a switching current of a power converter. The controller comprises a first circuit to generate a first signal in response to the switching current of a transformer of the power converter. A second circuit is coupled to the transformer to generate a second signal in response to a discharging time of the transformer. A third circuit is used for generating a third signal by integrating the first signal with the second signal. A switching circuit generates a switching signal in response to the third signal and a reference voltage, in which the switching signal is used to switch the transformer and regulates the output current of the power converter. In order to achieve a precisely output current control, a time constant of the third circuit is designed to correlate to the switching frequency of the switching signal.
