ABSTRACT:
A power converter including a switching transformer having a primary winding and a secondary winding, the secondary winding having first and second voltage nodes across which a winding voltage having a variable duty cycle and phase is impressed; a first synchronous rectifier transistor coupled from the first voltage node to a common node; a second synchronous rectifier transistor coupled from the second voltage node to the common node; and a driver circuit operable to receive the winding voltage and produce first and second drive signals to the first and second synchronous rectifier transistors, respectively, the first and second drive signals leading the phase of the winding voltage.
