1. A DC-DC converter comprising:

  • converting means for converting a first DC voltage to a converted DC voltage; and

    power conservation means having hysteresis for powering on said converting means in response to the converted DC voltage being less than a minimum voltage, and for powering off said converting means in response to the converted DC voltage being greater than a maximum voltage, said converting means comprising;

    switching means for increasing the current flow through an inductor;

    current sensing means for sensing the current flow through the inductor;

    regulating means governed by said current sensing means to control said switching means in response to the current flow through the inductor exceeding a predetermined value, thereby regulating the current flow through the inductor;

    voltage storage means for storing the converted DC voltage;

    rectifying means having an input coupled to said switching means and an output coupled to said voltage storage means; and

    timing means for periodically activating said switching means, wherein the inductor has an input coupled to a voltage source and an output coupled to said switching means and said rectifying means, and wherein the switching means couples the output of the inductor to a common potential when activated, and decouple the output of the inductor from the common potential when deactivated.
