Abstract
An optical communication system includes a light source and an output capacitor coupled to the light source. The system also includes a switching converter circuit coupled to the output capacitor. The switching converter circuit is configured to provide an output voltage to the output capacitor based on an active mode and a power-save mode. The switching converter circuit includes a controller configured to perform pulse gating in the power-save mode based on a timer and a comparison of the output voltage with a voltage threshold.
