Abstract
According to one aspect, an integrated circuit to control a power supply that supplies power to a plurality of light-emitting diode (LED) strings is provided. The integrated circuit includes an interface circuit to couple to a plurality of serial shift registers that are coupled in a daisy chain. The interface circuit may be configured to receive a plurality of digital values from the plurality of serial shift registers each corresponding to a voltage level at one end of an LED string of the plurality of LED strings and identify a lowest digital value from the plurality of digital values. The integrated circuit may further includes a converter coupled to the interface circuit that is configured to convert the lowest digital value into a control signal and provide the control signal to the power supply to adjust an output voltage of the power supply.
