LTC3108-1 Ultralow Voltage Step-Up Converter and Power Manager - Ultra-low input energy harvesting: Upward topology accepts input from sources down to 20 mV, ideal for thermoelectric generators (TEGs), thermopiles, and small solar cells. - Integrated energy management: High level of integration with a small boost transformer provides a complete power management solution for wireless sensing and data acquisition. - MCU and radio support: The 2.2 V rail powers an external microprocessor, while the main output can be programmed to one of four fixed voltages to power a wireless transmitter or sensors. - Monitoring and control: A Power-Good indicator shows when the main output is within specification. A second output can be activated by the host. - Development board: Ultralow voltage step-up converter and power manager development board for rapid prototyping and testing. Use scenarios - Scenario 1: Harvest energy from a thermoelectric generator to power a wireless sensor and transmitter, using the 2.2 V MCU rail and a fixed main-output for the radio. - Scenario 2: A small solar cell powers a data logger and sensor network, with four fixed main-output voltages to support sensors and interface electronics; the host can activate the second output as needed. - Scenario 3: Prototyping energy-harvesting wireless nodes; evaluate performance and use the host-controlled second output for peripherals.
