Abstract
A cascode switch includes a first power transistor configured to be coupled to a load and a second power transistor coupled in series with the first power transistor so that the second power transistor is between ground and the first power transistor. The second power transistor is operable to switch on and off responsive to a pulse source coupled to a gate of the second power transistor. The first power transistor is operable to switch on and off responsive to the same pulse source as the second power transistor or a DC source coupled to a gate of the first power transistor. Alternatively or in addition, a transistor device is coupled to the gate of the first power transistor and operable to actively turn off the first power transistor independent of the load current.
