This disclosure includes novel ways of implementing a power supply that powers a load. More specifically, a power supply includes a controller. The controller controls operation of a first power converter stage and a second power converter stage to convert an input voltage into an output voltage. For example, the first power converter stage is operative to receive an input voltage and convert the input voltage into an intermediate voltage. The second power converter stage such as a transformer-less switched-capacitor converter is coupled to the first power converter stage. The second power converter stage receives the intermediate voltage and converts the intermediate voltage into an output voltage to power a load.
