ABSTRACT:
A power supply supplies an output current to an integrated circuit having at least one circuit block. The at least one circuit block has an operating mode controllable in response to an enable signal or a clock signal. The integrated circuit receives a load current to power the circuit block as a function of the operating mode of the circuit block. The load current is a portion of the output current. A receiver receives a weighted signal. The weighted signal is a function of the enable signal and the clock signal to indicate an expected load current of the integrated circuit. A controller controls the output current of the power supply as a function of the expected load current of the integrated circuit such that the power supply pre-emptively changes the output current.
