Abstract: A switch includes a power transistor configured to switch an input voltage to a load. The switch further includes a charge pump and a duty cycle controller. The charge pump is coupled to the power transistor and includes an enable input to cause the charge pump to be turned on and off. The duty cycle controller is coupled to the charge pump and is configured to duty cycle the charge pump based on a comparison of a signal of a gate of the power transistor to a reference signal.
