DUAL VOLTAGE POWER SUPPLY

摘要

A power supply for an integrated circuit has first and second energy storage elements and a regulator. The first energy storage element stores energy for application to the integrated circuit. The second energy storage element stores energy at a higher voltage than the energy stored by the first energy storage element. The regulator interconnects the energy storage elements and controls the flow of energy from the second energy storage element to the first energy storage element to regulate the voltage level of the energy stored in the first energy storage element.
