Patent ID: 8531123

Claim:
A DC/DC converter comprising: a transformer having a primary winding coupled to a power source, a first secondary winding operable for providing a first output voltage and a second secondary winding operable for providing a second output voltage; a first controller coupled to said primary winding and operable 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 operable 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, wherein the DC/DC converter further comprises a driver controller coupled to said first switch and operable for generating said pulse modulation signal to control said first switch, wherein said first output voltage is supplied to a first load and said second output voltage is supplied to a second load, and wherein said driver controller is operable for generating said pulse modulation signal based on a power requirement of said second load.
