Abstract
A power converter includes a switch control circuit for driving a high side switch of the power converter comprising the high side switch and a low side switch connected in series. The switch control circuit may have a first terminal for receiving an input signal, a second terminal used as a reference ground terminal of the switch control circuit, and a third terminal used as an output terminal to provide a driving signal, the switch control circuit can draw power from the input signal and may be configured to control a logic state of the driving signal based on a logic state of the input signal relative to a reference ground signal at the second terminal or based on a current flowing through the first terminal.
