LTC3109  
Auto-Polarity, Ultralow  
Voltage Step-Up Converter  
and Power Manager  
DescripTion  
TheLTC®3109isahighlyintegratedDC/DCconverterideal  
for harvesting surplus energy from extremely low input  
voltage sources such as TEGs (thermoelectric genera-  
tors) and thermopiles. Its unique, proprietary autopolarity  
topology* allows it to operate from input voltages as low  
as 30mV, regardless of polarity.

System  
– SeleAtable V

OUT  
Using two compact step-up transformers and external  
energy storage elements, the LTC3109 provides a com-  
plete power management solution for wireless sensing  
and data acquisition. The 2.2V LDO can power an external  
microprocessor,whilethemainoutputcanbeprogrammed  
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 quies-  
cent current and high efficiency maximizes the harvested  
energy available for the application.
