Product Overview

The LTC3109IGN#PBF 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 auto polarity topology allows it to operate from input voltages as low as 30mV, regardless of polarity. Using two compact step-up transformers and external energy storage elements, the LTC3109 provides a complete power management solution for wireless sensing and data acquisition. The 2.2V LDO can power an external microprocessor, while the main output can be programmed to one of four fixed voltages. The power good indicator signals that the main output is within regulation. A second output can be enabled by the host. A storage capacitor (or battery) can also be charged to provide power when the input voltage source is unavailable. Extremely low quiescent current and high efficiency maximizes the harvested energy available for the application.
  • Less than ±1°C needed across TEG to harvest energy
  • Proprietary auto-polarity architecture
  • Power good indicator
  • Uses compact step-up transformers
