Abstract
A power switch, including: a PFET including a gate, a source coupled to a source voltage, and a drain for outputting a supply voltage; and a level shifter, wherein the level shifter includes: an input node for receiving an input voltage, wherein the input voltage includes first and second voltage levels; a supply node for receiving the supply voltage, wherein the supply voltage includes third and fourth voltage levels; and an output node for outputting an output voltage, wherein the output node is coupled to the gate of the PFET; wherein, when the input voltage is at the first voltage level, the output voltage is at the first voltage level and the PFET is in a conducting state; and wherein a voltage between the gate and drain of the PFET and a voltage between the gate and source of the FET do not exceed a maximum voltage of the PFET.
