1. A DC/DC converter comprising:

  • a transformer having a primary winding coupled to a power source, a first secondary winding for providing a first output voltage and a second secondary winding for providing a second output voltage;

    a first controller coupled to said primary winding for controlling input power to said primary winding to regulate said first output voltage; and

    a first switch coupled to said second secondary winding and for regulating said second output voltage,wherein said first switch is controlled by a pulse modulation signal, wherein a current flows through said second secondary winding if said pulse modulation signal is in said first state, and wherein said current flowing through said second secondary winding remains cut-off if said pulse modulation signal is in said second state.
