1. A power converter, comprising:

  • a first circuit converting an AC input voltage to a first predetermined DC output voltage;

    a second circuit converting a DC input voltage to a second predetermined DC output voltage; and

    a third circuit having a feedback circuit comprising a single feedback loop, said third circuit receiving said first and second predetermined output voltages and providing a selectable DC output voltage at a first output, wherein said single feedback loop is adapted to regulate both said first and second circuits to provide said selectable DC output voltage when said AC and DC input voltages are supplied to respective said first and second circuits.
