Abstract
Embodiments of a power switching system are disclosed. In some embodiments, the power switching system includes a power transistor, a current buffer, and a driver circuit. The power transistor has a first control terminal, a first transistor terminal, and a second transistor terminal. The current buffer is configured as a current amplifier that results in a voltage at the first control terminal. The current buffer has a second control terminal. The driver circuit has a first circuit branch connected to the second control terminal and a second circuit branch connected to the second control terminal. The first circuit branch includes a first switch for opening and closing the first circuit branch. The second circuit branch includes a second switch and a current source, wherein the second switch is configured to open and close the second circuit branch.
