Abstract
An active feedback control integrated circuit applied to an alternating current/direct current converter includes a feedback pin, an operation unit, a control unit, and a controlled-current generation unit. The feedback pin is used for receiving a feedback current of an output feedback unit of the alternating current/direct current converter. The operation unit is used for generating an operation signal according to the feedback current. The control unit is coupled to the operation unit for generating a current control signal. The controlled-current generation unit is coupled to the control unit for generating a controlled current to the feedback pin according to the current control signal.
