What are the key features of LTC3108IGN#PBF?
- Operates from input voltages as low as 20 mV, enabling energy harvesting from thermoelectric generators and small temperature differentials
- Selectable output voltages of 2.35 V, 3.3 V, 4.1 V, and 5 V supporting a wide range of wireless sensor node supply requirements
- Integrated power manager with LDO and auxiliary output pin simplifying multi-rail energy harvesting power supply designs
- 16-pin SSOP package enabling compact PCB implementation in space-constrained IoT and wearable energy harvesting modules
What is LTC3108IGN#PBF used for?
The LTC3108IGN#PBF is designed for energy harvesting systems that capture power from low-voltage sources such as thermoelectric generators, small solar cells, and vibrational piezoelectric elements in the 20 mV to 500 mV range. It is well suited for autonomous wireless sensor nodes in building automation and industrial monitoring where battery replacement is impractical, converting waste heat gradients of just a few degrees Celsius into usable supply voltages. The selectable output voltage and integrated power management simplify the design of self-powered IoT devices that must cold-start from near-zero energy reserves.

Frequently Asked Questions
How low an input voltage can the LTC3108IGN#PBF start up from and what energy source enables that?
The LTC3108IGN#PBF can begin operating from input voltages as low as 20 mV, which corresponds to the output of a thermoelectric generator placed across a temperature gradient of less than 1°C in many Peltier module configurations. This capability makes it unique among boost converters for harvesting energy from small industrial temperature differentials or body heat in wearable sensors.
What regulated output voltages does the LTC3108IGN#PBF provide and how are they selected?
The device offers four selectable output voltages—2.35 V, 3.3 V, 4.1 V, and 5 V—chosen by logic-level signals on two VS input pins. This flexibility allows a single BOM line item to power sub-1 V microcontrollers, 3.3 V RF transceivers, or 5 V sensors depending on the target application without redesigning the power stage.
For an industrial wireless sensor node, how does the LTC3108IGN#PBF eliminate the need for battery replacement?
By harvesting thermal energy from pipe surfaces or motor housings where temperature differentials of 5°C to 20°C exist, the LTC3108IGN#PBF can continuously supply a low-power sensor MCU at 3.3 V with tens of microwatts of output power. When combined with a storage capacitor or thin-film battery, this allows indefinite maintenance-free operation without primary batteries in always-on industrial monitoring applications.
What is the maximum input voltage the LTC3108IGN#PBF supports and what happens if the source exceeds that?
The converter accepts a maximum input voltage of 500 mV. Exceeding this voltage risks damaging the internal low-voltage CMOS process transistors, so a simple series resistor or Zener clamp is recommended when the harvesting source can transiently exceed 500 mV, such as during startup of a solar panel in full sunlight delivering open-circuit voltages above the operating range.
