Summary:A power supply is disclosed. The power supply includes a first switch and a second switch. The gate of the first switch is coupled to the gate of the second switch. The power supply further includes a cutoff switch coupled between the first switch and an input voltage port. A comparator is included for comparing a voltage at a feedback port with a fixed reference voltage. The comparator opens the cutoff switch when the voltage at the feedback port is lower than the fixed reference voltage.
