LTC3108

Ultralow Voltage Step-Up

Converter and Power Manager

FEATURES

DESCRIPTION

The LTC^®3108 is a highly integrated DC/DC converter

ideal for harvesting and managing surplus energy from

extremely low input voltage sources such as TEGs (ther-

moelectric generators), thermopiles and small solar cells.

The step-up topology operates from input voltages as

low as 20mV. The LTC3108 is functionally equivalent to

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

the LTC3108-1 except for its unique fixed V

options.

OUT

Power Good Indicator

Using a small step-up transformer, the LTC3108 provides

a complete power management solution for wireless

sensing and data acquisition. The 2.2V LDO powers an

external microprocessor, while the main output is pro-

grammed to one of four fixed voltages to power a wire-

less transmitter or sensors. The power good indicator

signals that the main output voltage is within regulation.

A second output can be 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.
