Abstract
A power switch comprising: a cascode having a normally ON transistor connected in series with a normally OFF transistor at a cascode node: a first diode connected between a gate of the normally ON transistor and a first ground common to the cascode and the diode; and a controller comprising: a controller power supply having a power supply output connected to the cascode node at which output the controller power supply provides a voltage relative to a second ground that is floating relative to the first ground; and a first controller output connected to the gate of the normally ON transistor at which the controller generates a first voltage relative to the second ground.
