1. A power management integrated circuit, comprising:
a first electric power converter;
a second electric power converter;
selection circuitry coupled to the first electric power converter and the second electric power converter, the selection circuitry configured to toggle between activating the first electric power converter and the second electric power converter; and
a controller configured to determine a load on the power management integrated circuit based on gamma-decoded image data and a coefficient corresponding to a display brightness value and, in response to determining the load on the power management integrated circuit, send a selection signal to the selection circuitry indicating a selection of the first electric power converter or the second electric power converter.
