Energy harvesting DC-DC converter

8 October 2014 Power Electronics / Power Management

Linear Technology’s LTC3331 is a complete energy harvesting solution that delivers up to 50 mA of continuous output current to extend battery life when harvestable energy is available. A simple 10 mA shunt enables charging of a rechargeable battery with harvested energy while a low-battery disconnect function protects the battery from deep discharge. The IC requires only 200 nA of supply current from the battery when providing regulated power to the load from harvested energy and only 950 nA operating when powered from the battery under no-load conditions. It also integrates a synchronous buck-boost DC-DC converter powered by a rechargeable battery.
