Embodiments of the invention provide a DC/DC converter. The DC/DC converter includes a transformer, a switch controller and a driver controller. The transformer has a primary winding coupled to a power source, a first secondary winding provides a first output voltage to a first load, and a second secondary winding provides a second output voltage to a second load. The switch controller is coupled to the primary winding and controls a first switch coupled to the primary winding to control input power to the primary winding and to regulate the first output voltage based on a power requirement of the first load. The driver controller is coupled to the second secondary winding and generates a pulse modulation signal to alternately turn on and turn off a second switch coupled to the second secondary winding to regulate the second output voltage based on a power requirement of the second load.
