Energy Harvester Operates from Small Temperature Differentials of Either Polarity

Jun 11th 2010
The LTC3109 is a highly integrated DC/DC converter ideal for harvesting surplus energy from extremely low input voltage sources such as TEGs (thermoelectric generators) and thermopiles. Its unique, proprietary autopolarity topology allows it to operate from input voltages as low as 30mV, regardless of polarity. In this circuit, ...
