| Analog eLab: Extend the Operating Range for Solar/Single-Cell Applications |

Overview:
Extend the Operating Range for Solar/Single-Cell Applications
The quest to achieve ever-lower operating voltage and lower power consumption levels in circuit design is a trend producing difficult challenges for electrical engineers as they run up against the very constraints placed upon them by basic semiconductor device characteristics. These characteristics, long been viewed by engineers as fundamental, may have prevented them from maximizing the usable voltage range that would otherwise make a novel circuit successful. For example, solar-cell designs and the challenge of meeting the ultra-low operating voltage of the fuel cell. In many applications, the nominal voltage is 0.3V per cell. Another example of a key constraint is dealing with the generation of a standard 3.3V or 5V output from a solar-cell array in a parallel configuration. This analog workshop will highlight new options for generating lower operating voltages in circuit designs. It is intended to stimulate new ways of thinking about circuit design and how the latest generation of synchronous boost converters can be implemented to achieve results that were either unattainable or highly improbable. The lab segment will demonstrate a boost converter in solar panel application.
