ABSTRACT:
A current-level controlling device for a power supply includes a reception end for receiving a current sense signal, a reference voltage generator for generating a reference voltage, an adaptive reference voltage generator, coupled to the reference voltage generator and the reception end, for adjusting the reference voltage according to variation of peak values of the current sense signal, so as to generate an adaptive reference voltage, a comparator, coupled to the reception end and the adaptive reference voltage generator, for comparing the current sense signal and the adaptive reference voltage, to generate a comparison result, and a control unit, coupled to the comparator, for controlling a switch transistor of the power supply according to the comparison result.
