Abstract: A charging integrated circuit for use in an electronic device may include an input interface configured to receive input electrical energy from a power supply, wherein the input interface is controllable to modify characteristics of the input electrical energy to provide a supply voltage, an N-level power converter configured to receive the supply voltage based on the input electrical energy and generate an output voltage, and a controller configured to control characteristics of the input electrical energy to maximize power efficiency associated with at least one of the charging integrated circuit and the electronic device and control the input interface to adjust the supply voltage such that the output voltage of the power converter is substantially unequal to M times the supply voltage divided by (N−1), where M is a positive integer less than (N−1).
