1. A current control circuit configured to regulate a power source having an output connected to a load, the current control circuit comprising:

  • a current sensing circuit configured to provide a current feedback signal as a function of a level of current flow from the output of the power source;

    a current amplifier having a first input configured to receive the current feedback signal, a second input configured to receive a reference voltage, and an output configured to provide a current amplifier output signal as a function of the difference between the current feedback signal and the reference voltage;

    a coupling circuit configured to receive the current amplifier output signal and to produce a coupling signal as a function of the current amplifier output signal to a voltage regulation error amplifier configured to receive the sum of the coupling signal and the feedback signal.
