ABSTRACT:
In accordance with an aspect of the present invention, an external FET driving circuit includes a driving portion, a drain-to-gate clamp portion and a current feedback portion. The driving portion provides a driving signal to the external FET. The drain-to-gate clamp portion protects the external FET from flyback current, when the external FET is quickly turned OFF. The current feedback portion controls the driving signal provided by the driver.
