1. A power supply comprising:

  • a switched capacitor array comprising of switches and capacitors;

    a first terminal of the switched capacitor array coupled to a first terminal of a magnetic storage element;

    wherein the capacitors in the switched capacitor array are charged and discharged with a current flowing through the magnetic storage element;

    wherein voltages on the capacitors in the switched capacitor array are regulated by changing a time duration of the current flowing through the capacitors in the switched capacitor array;

    wherein the time duration is changed repetitively in steady state of operation by changing a time position of a leading edge of a first signal which turns on a first switch in the switched capacitor array wherein the turning on of the first switch in the switched capacitor array causes current in the magnetic storage element to increase.
