LTC3108 Overview

Part: LTC3108EDE — Linear Technology Corporation

Type: Ultralow Voltage Step-Up Converter and Power Manager

Description: A highly integrated DC/DC converter optimized for harvesting and managing energy from extremely low input voltage sources, operating from input voltages as low as 20mV, and designed to accumulate and manage energy for short bursts of power.

Operating Conditions:

  • Supply voltage: 50mV–400mV (Typical no load start-up = 20mV)
  • VOUT: Jumper Selectable from 2.35 to 5.0V

Key Specs:

  • Input Voltage Range: 50mV–400mV
  • Typical no load start-up voltage: 20mV
  • VLDO output voltage: 2.2V
  • VOUT output voltage: Jumper Selectable from 2.35 to 5.0V
  • VOUT2 output voltage: VOUT (switched output)
  • VSTORE voltage: 5.25V

Features:

  • Optimized for harvesting and managing energy from extremely low input voltage sources
  • Step-up topology operates from input voltages as low as 20mV
  • Designed to accumulate and manage energy over a long period for short bursts of power
  • Multiple output voltages (VLDO, VOUT, VOUT2, VSTORE)

Applications:

  • Harvesting and managing energy from extremely low input voltage sources such as thermoelectric generators (TEG)
