A DC to DC converter comprising an energy storage element comprising an energy
storage element input and an energy storage element output the energy storage element
input coupled to receive a first power level and the energy storage element output
providing a second power level. The converter also comprises a feedback circuit
comprising a feedback input and a feedback output, the feedback input coupled to
the energy storage element output. The converter further comprises a regulator
circuit comprising a regulator circuit feedback input and a regulator circuit output,
the regulator circuit feedback input coupled to the feedback output and the regulator
circuit output coupled to the energy storage element input, the regulator circuit
regulating the input of the first power level to the energy storage element input.
When a signal at the regulator circuit feedback input is above a threshold level
the regulator circuit ceasing operation and when the signal at the regulator circuit
feedback input is below the threshold level the regulator circuit is enabled.
