Abstract
A power line communication driver circuit drives a power communication line with a power line communication signal that supplies both power and control data to a plurality of electronic devices. The power line communication driver circuit includes a ramp generator that receives an input signal encoding digital data and generates a ramp signal that switches between a low non-zero ramp voltage and a high ramp voltage to encode the digital data. The power line communication driver circuit furthermore includes a buffer circuit that receives and buffers the ramp signal to generate the power line communication signal. In one application, the power line communication driver circuit may drive a group of zone integrated circuits that include driver circuits for driving respective LED zones of a display device.
