Abstract
A DC-DC power converter has a transformer with a primary side and secondary side. A first power transistor is coupled between a first end of a first winding of the secondary side and a ground terminal. A second power transistor is coupled between a second end of the first winding and the ground terminal. A first driver transistor is coupled to a gate of the first power transistor, and a second driver transistor is coupled to a gate of the second power transistor. A separate driver winding taken off the secondary side of the transformer controls the gates of the first and second driver transistors. First and second inductors are coupled between the opposite ends of the first winding and an output of the power supply. First and second resistors are coupled between the gates of the first and second driver transistors and the ground terminal, respectively.
