Abstract
Methods, devices, and integrated circuits are disclosed for a driver controller that determines whether an input is AC or DC and controls a driver in either an AC-adapted control mode or a DC-adapted control mode. An example method includes detecting whether an input is primarily AC or DC. The method further includes controlling an output current in an AC-adapted control mode in response to detecting that the input is primarily AC, and controlling the output current in a DC-adapted control mode in response to detecting that the input is primarily DC.
