A synchronous converter including a control module including a pulse generator configured to produce a pulse. An input port suitable for receiving an input voltage from a voltage source, is couple to a first conversion stage of the converter. The first conversion stage preferably includes a first pair of transistors, a first stage capacitor, and a first winding of a coupled inductor. The first pair of transistors are preferably driven by the control module pulse generator such that the first conversion stage is coupled to the input port during the first interval of the pulse and isolated from the input port during the second interval of the pulse and the gain of the first conversion stage is approximately equal to the duty cycle of the pulse. The converter further includes a second conversion stage preferably including a second pair of transistors, a second stage capacitor, and a second winding of the coupled inductor. The second pair of transistors are preferably driven by the control module pulse generator such that the second conversion stage is coupled to the first conversion stage output during the first interval and isolated from the first conversion stage during the second interval. The gain of the second conversion stage, like the first stage, is approximately equal to the duty cycle of the pulse generator. The first and second conversion stages are coupled by the common inductive core of the coupled inductor.
