Abstract
In accordance with an embodiment, a method of operating a switched-mode power supply includes synchronously rectifying a current in a secondary side of the switched-mode power supply by detecting a voltage drop of a secondary winding of a transformer and activating a semiconductor switch coupled to the secondary winding when the voltage drop is detected. The method also includes determining a digital signal transmitting the digital signal to a controller coupled to a primary winding of the transformer by switching the semiconductor switch in accordance with the digital signal.
