Linear Technology Multi-Source Energy Harvester







The “Energy Harvesting Solution To Go” provides the following benefits:

  • Complete solution of harvesting energy, energy management and storage  
  • Easy transfer of the provided solutions to your design  
  • Evaluation of the highest efficient components in the market



  • 4 harvesters for different source types
  • On-board solar cell and thermo electric generator
  • Connectors for optional external generators

Quick Start

  • Decide for your energy harvesting source
  • Set the appropriate jumper JP1 to JP4 to feed the harvested source to the power connector.
  • Optionally set jumper JP9 to ON for an extended buffer capacitance for all harvesters or set jumper JP10 to ON for an extended buffer capacitance for the TEG harvester
  • Connect your application to the power connector
