Abstract
A control integrated circuit for a power factor correction converter has a pin for detecting an alternating-current information and a direct-current information of an input signal. The control integrated circuit comprises a signal peak detector for detecting a peak value of the input signal to the pin to obtain the direct-current information of the input signal. Since the alternating-current information and the direct-current information of the input signal can be obtained through the same pin, the pin count of the control integrated circuit can be decreased.
