1. A power management system comprising:

  • a power conversion stage comprising a first terminal coupled to a first power source which has a first voltage and comprising a second terminal selectively coupled to a second power source which has a second voltage; and

    a controller coupled to said power conversion stage operable for selecting a mode from at least a first mode and a second mode,wherein in said first mode said power conversion stage receives said first voltage at said first terminal and generates a step-up voltage at said second terminal, and wherein in said second mode said power conversion stage receives said second voltage at said second terminal and generates a step-down voltage at said first terminal for charging said first power source, and wherein said step-up voltage is greater than said first voltage and said step-down voltage is less than said second voltage.
