METHOD FOR PERFORMING ADAPTIVE INPUT CURRENT CONTROL IN AN ELECTRONIC DEVICE WITH AID OF ADAPTOR MANAGEMENT, AND ASSOCIATED APPARATUS

摘要

A method and apparatus (100) for performing adaptive input current control in an electronic device (100) are provided, where the method includes the steps of: before limiting an input current (I IN ) of a regulator (105) of the electronic device to a target current value, monitoring the input current (I IN ) of the regulator (105) according to a reference current (I REF ), and decreasing the reference current (I REF ), to indicate that the reference current (I REF ) changes starting from one of a plurality of predetermined reference current values, wherein the input current (I IN ) is obtained from a power source; detecting an input voltage (V IN ) of the regulator (105) to generate a detection signal (V DET ), to selectively trigger limiting output power of the regulator (105); and at a time point when the reference current (I REF ) becomes smaller than the input current (I IN ), limiting the input current (I IN ) of the regulator (105) to the target current value with a latest reference current value of the reference current (I REF ) being utilized as the target current value.
