The LTC
The LTC3107 is a highly integrated DC/DC converter designed to extend the life of a primary battery in low power wireless systems. It achieves this by harvesting and managing surplus energy from extremely low input voltage sources, such as Thermoelectric Generators (TEGs) and thermopiles. The device utilizes a step-up topology capable of operating from input voltages as low as 20mV.
