Abstract: A power stage for a DC-to-DC voltage converter includes a voltage input, a high-side n-channel transistor, a high-side p-channel transistor, and a low-side n-channel transistor. The voltage input is couplable to a supply voltage. The drain terminal of the high-side n-channel transistor is coupled to the voltage input and the source terminal is coupled to a first node that is couplable to an output stage of the DC-to-DC converter. The source terminal of the high-side p-channel transistor is coupled to the voltage input and the drain terminal is coupled to the first node. The drain terminal of the low-side n-channel transistor is coupled to the first node and the source terminal is coupled to a ground.
