This disclosure includes systems, methods, and techniques for controlling delivery of power to one or more strings of light-emitting diodes (LEDs). For example, a circuit includes a power converter unit configured to receive an input signal from a power source and generate a first output signal comprising a first voltage, a charge pump configured to receive at least a portion of the first output signal from the power converter unit and generate a second output signal comprising a second voltage, and a linear regulator configured to receive the second output signal from the charge pump and generate a third output signal comprising a third voltage.
