Abstract

Switching circuits, half-bridge power converters, and methods for operating a switching circuit including a switching transistor coupled to a load. The method includes applying, with a driver, a gate voltage to the switching transistor. The method also includes generating, with a feedback capacitor, a feedback current based on a change in a voltage sensed at a drain terminal of the switching transistor when the switching transistor turns on. The method further includes applying the feedback current to the driver to limit the gate voltage applied to the switching transistor. The method also includes adjusting, with a controller, a switching slew rate of the switching transistor by draining an amount of the feedback current.
