1. An electronic ballast control for controlling a power switch in an electronic ballast to switch power to a load, comprising:

  • a storage device for storing parameters to operate ballast control components;

    a control device coupled to the storage device for reading parameters from the storage device and providing the parameters to the ballast control components;

    an oscillator coupled to the control device for receiving the parameters from the control device and providing an oscillation signal based on the received parameters;

    an output section coupled to the oscillator and operable to receive the oscillation signal and produce signals for operating the power switch;

    wherein the control is implemented as a single integrated circuit; and

    further comprising a minimum frequency signal applied to the oscillator to determine a minimum oscillation frequency provided by the oscillator.
