Abstract
A switch for controlling a power supply and a method of operating the switch are disclosed. The switch includes a first transistor having a drain and a source connected between Vand Vand a gate connected to be driven to a first voltage that is greater than V, an external capacitor operable, when connected to the gate of the first transistor, to control a rise time of V, and a circuit coupled to the gate of the first transistor and to the external capacitor, the circuit connected to couple the external capacitor to the gate of the first transistor responsive to an enable signal turning on and to uncouple the external capacitor from the gate of the first transistor responsive to the voltage on the gate reaching the first voltage.
