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

Using a small step-up transformer, the LTC3107 provides a complete power management solution for typical wireless sensor applications that operate from a primary battery. The 2.2V LDO can be used to power an external microprocessor, while the main output voltage automatically adapts to match the voltage of the primary battery. The LTC3107 seamlessly transitions from battery power to harvested power whenever harvested energy is available, extending the life of the battery. The BAT_OFF indicator can be used to track battery usage. An optional storage capacitor accumulates excess harvested energy, further extending battery life.

The LTC3107 is available in a small, thermally enhanced 10-lead (3mm × 3mm) DFN package.

Dust Energy Harvesting Demo Board with E-Ink Display, Designed to Connect to the DC2344A or DC2509A

Product Detail

Demonstration circuit 2321A is a low power wireless sensor node development platform equipped with an E-ink display for user feedback. The system is capable of monitoring and managing its available energy, logging information from sensors and sharing this data over a wireless network.


The board is designed to connect to the DC2344A or DC2509A energy harvesting demonstration boards which output a regulated power supply as well as status information from energy harvesting ICs and their backup batteries. Two coulomb counters on the DC2321A allow the processor to monitor the energy output of these batteries which will vary depending on the amount of energy which can be harvested from the system’s surroundings.


A DC2274A-A SmartMesh Manager must be used in order to evaluate the networking features of the DC2321A.
