Low-loss LED driver improves a system's green footprint by boosting efficiency and extending battery life

Posted: 23 Jul 2009 ?? ?Print Version ?Bookmark and Share

Keywords:high-brightness LED? battery? green? energy efficiency?

Providing power to drive high-brightness LEDs (HB LEDs) can be achieved by a number of different schemes. Because many systems are battery powered, energy efficiency is key to maximizing each battery charge and the system's operating time. By improving battery efficiency, you also improve the system's "green" footprint. Over the life of the battery for the same number of charge cycles, longer times between charges translate into potentially hundreds of hours of additional use from the batteries. Thus fewer batteries may end up in landfills or hazardous waste-disposal sites.
