Abstract
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 is configured to monitor current through one or more strings of LEDs. The circuit includes a power converter unit, where the power converter unit is configured to receive an input signal from a power source, and where the power converter unit is configured to deliver an output signal to the one or more strings of LEDs, and a set point unit configured to deliver a set point signal to the power converter unit. Additionally, the circuit includes a correction unit configured to deliver, based on an input parameter value, an output parameter value, and a set point parameter value, a correction signal to the power converter unit.
