A switch mode power converter with selectable power paths is described herein. The switch mode power converter comprises a plurality of stacked secondary windings and secondary side circuitry. The plurality of stacked secondary windings comprises a first winding and a second winding. Additionally, the secondary side circuitry comprises a first power path, a second power path, and a power multiplexer (MUX). The first power path is electrically coupled to the first winding; and the second power path is electrically coupled to the second winding. The power MUX is configured to select and transition between the first power path and the second power path to provide a single output power path to a load.
