In an example aspect, the integrated circuit includes a first power rail, a second power rail, a load power rail, multiple power-multiplexer tiles, and power-multiplexer control circuitry. The first power rail is at a first voltage, and the second power rail is at a second voltage. The multiple power-multiplexer tiles are coupled in series in a chained arrangement and jointly perform a power-multiplexing operation responsive to a power-rail switching signal. Each power multiplexer tile switches between coupling the load power rail to the first power rail and the second power rail. The power-multiplexer control circuitry is coupled to the first and second power rails and includes a comparator to produce a relative voltage signal based on the first and second voltages. The power-multiplexer control circuitry generates the power-rail switching signal based on the relative voltage signal.
