LTC3108 ultra low voltage boost converter

Introducing the LTC3108, a module designed for energy harvesting at low voltage levels.

Introducing the LTC3108 ultra low voltage boost converter designed for Linear Technologies’ LTC3108 IC. This highly integrated converter, known as the LTC3108-1, is perfect for harvesting and regulating surplus energy from extremely low input voltage sources like TEGs, thermopiles, and small solar cells. Its step-up topology enables operation from input voltages as low as 20mV.

Utilizing a compact step-up transformer, the LTC3108 ultra low voltage boost converter offers a comprehensive solution for managing power in wireless sensing and data acquisition systems. An external microprocessor is powered by the 2.2V LDO, while the main output can be set to one of four pre-programmed voltages for powering sensors or a wireless transmitter. The power good indicator indicates that the main output voltage is within regulation. The host can also activate a second output, and a storage capacitor ensures uninterrupted power even when the input voltage source is unavailable. The LTC3108 ultra low voltage boost converter boasts minimal quiescent current and an efficient design, resulting in quick charging of the output reservoir capacitor. It should be noted that the LTC3108-1 differs from the LTC3108 solely in its fixed VOUT options.
