A light control module (LCM) in accordance with one embodiment, includes terminals configured to receive a supply voltage, and a switching converter configured to receive the supply voltage and to provide an output voltage at an output node, wherein the output voltage and the supply voltage have different polarities. Further, the LCM includes an output terminal coupled to the output node of the switching converter and configured to sink a load current from a LED module.

Light control module for driving LED modules

In some examples, a circuit is configured to generate a first signal based at least in part on an input signal, wherein the first signal comprises a common mode signal and a load signal. The circuit is further configured to generate a second signal based at least in part on the input signal, wherein the second signal comprises an inverted version of the common mode signal. The circuit is further configured to apply the first signal and the second signal to a load.
