1. A converter system, comprising:

  • a converter power stage that can operate in a Discontinuous Conduction Mode (DCM) in a range of output currents and a Continuous Conduction Mode (CCM) in another range of output currents wherein the converter power stage includes at least an inductor with an inductor value and a control switch and the converter power stage provides an average current, anda current controller coupled to the converter power stage; and

    wherein when the converter power stage operates in DCM, the converter power stage provides the average current and wherein the current controller is configured to measure the inductor value of the inductor.
