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.
