Abstract: A DC-DC converter includes a current sense circuit. The current sense circuit includes a sense current output, an inductor current measurement circuit, an inductor current emulation circuit, a first switch, and a second switch. The inductor current measurement circuit has an output. The inductor current emulation circuit has an output. The first switch is coupled between the output of the inductor current measurement circuit and the sense current output. The second switch is coupled between the output of the inductor current emulation circuit and the sense current output.

Abstract: Circuits for controlling a plurality of LEDs connected in series are disclosed herein. The circuit includes a plurality of switches, wherein each switch is connectable between the anode and cathode of one of the plurality of LEDs. Each of the switches has a first state wherein current does not pass through the switch and a second state wherein current passes through the switch. The circuit also includes an input for receiving data to program the switches and a data line for transferring data between a circuit controlling second LEDs that are connected in parallel with the first LEDs and the circuit. In addition, the circuit includes a data output for transferring data to other circuits controlling third LEDs that are connected in series with the first LEDs.
