The LTC3106 is a highly integrated, ultralow voltage buck-boost DC/DC converter with automatic PowerPath management optimized for multisource, low power systems. At no load, the LTC3106 draws only 1.6μA while creating an output voltage up to 5V from either input source.

If the primary power source is unavailable, the LTC3106 seamlessly switches to the backup power source. The LTC3106 is compatible with either rechargeable or primary cell batteries and can trickle charge a backup battery whenever there is an energy surplus available. Optional maximum power point control ensures power transfer is optimized between power source and load. The output voltage and backup voltage, VSTORE, are programmed digitally, reducing the required number of external components. Zero power Shelf Mode ensures that the backup battery will remain charged if left connected to the LTC3106 for an extended time.

Additional features include an accurate turn-on voltage, a power good indicator for VOUT, a user selectable 100mA peak current limit setting for lower power applications, thermal shutdown as well as user selectable backup power and output voltages.

LTC3106EUDC Demo Board | Buck-Boost, 0.35V ≤ VIN ≤ 5.1V; VOUT = 1.8/2.2/3.3/5V @ 300mA

Product Detail

Demonstration circuit DC2255A features the LTC3106, an ultralow input voltage buck-boost DC/DC converter with automatic PowerPath management optimized for multisource, low power systems. The DC2255A has four user-selectable output voltages: 1.8V, 2.2V, 3.3V and 5V. Output current can be up to 300mA (for VIN > VOUT). the LTC3106 operates with input voltages as low as 0.35V, and Burst Mode® operation architecture allows it to run very efficiently with as little as 1.6μA of input current at no load.

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.
