LTC3108

Ultralow Voltage Step-Up

Converter and Power Manager

FEATURES

DESCRIPTION

TheLTC^®3108isahighlyintegratedDC/DCconverterideal

forharvestingandmanagingsurplusenergyfromextremely

low input voltage sources such as TEG (thermoelectric

generators),thermopilesandsmallsolarcells.Thestep-up

topology operates from input voltages as low as 20mV.

Operates from Inputs of 20mV

Complete Energy Harvesting Power

Management System

- Selectable V

of 2.35V, 3.3V, 4.1V or 5V

OUT

- LDO: 2.2V at 3mA

- Logic Controlled Output

and data acquisition. The 2.2V LDO powers an external

microprocessor, while the main output is programmed to

one of four ﬁxed voltages to power a wireless transmitter

orsensors.Thepowergoodindicatorsignalsthatthemain

outputvoltageiswithinregulation.Asecondoutputcanbe

enabled by the host. A storage capacitor provides power

when the input voltage source is unavailable. Extremely

low quiescent current and high efﬁciency design ensure

the fastest possible charge times of the output reservoir

capacitor.
