Abstract
To reduce overall power consumption for an electronic display power management integrated circuit (PMIC), one of multiple electric power converters and/or electric power regulators may be selected based on an electrical load (e.g., due to the total brightness of the content displayed) on the electronic display at a given moment. In some embodiments, the PMIC may include a less efficient heavy load converter designed with high-current handling capability and a more efficient light load (e.g., low current) converter with lower current handling capability. A controller may dynamically select between the converters depending on a present load or an expected load on the electronic display.
