LTC3108EDE#PBF
Overview
The LTC3108EDE#PBF is a highly integrated DC/DC converter designed to harvest and manage surplus energy from extremely low input voltage sources such as TEGs (thermoelectric generators) and small solar cells. It features a unique step-up topology that operates from input voltages as low as 20mV, making it capable of extracting usable power from temperature differentials as small as 1 degree Celsius. The device includes a complete power management system with multiple regulated outputs to power microcontrollers and wireless sensors.
Why Choose This Part
The primary advantage is the ultralow start-up voltage of 20mV, which is significantly lower than standard boost converters. It integrates a MOSFET switch, a small-signal LDO, and a power manager with a storage capacitor controller into a single 4mm x 3mm DFN package, reducing the total bill of materials for energy harvesting systems.

Key Specifications
Getting Started
To evaluate this IC, use the DC1530A demonstration circuit which includes the necessary step-up transformer required for operation. Designers must select a transformer with a turns ratio (typically 1:20 to 1:100) matched to the expected input voltage range and required output current.
