Abstract
In described examples, an isolated DC-DC converter includes: an input node for receiving an input voltage; a transformer including first and second terminals; first and second low-side switches; and first and second high-side switches. The first low-side switch is coupled between the first terminal and a primary side ground. The second low-side switch is coupled between the second terminal and the primary side ground. The first high-side switch is coupled between the first terminal and the input node and is configured to be activated by a voltage at the second terminal. The second high-side switch is coupled between the second terminal and the input node and is configured to be activated by a voltage at the first terminal. Further, the isolated DC-DC converter includes a switch controller to cause the first and second voltages to alternatingly be zero by opening and closing the first and second low-side switches.
