DC2151A
Analog Devices Inc.
The LTC3331 integrates a high voltage energy harvesting power supply plus a buck-boost DC/DC powered from a rechargeable battery to create a single output supply for alternative energy applications. A 10mA shunt allows simple charging of the battery with harvested energy while a low battery disconnect function protects the battery from deep discharge. The energy harvesting power supply, consisting of an integrated full-wave bridge rectifier and a high voltage buck DC/DC, harvests energy from piezoelectric, solar, or magnetic sources. Either DC/DC converter can deliver energy to a single output. The buck operates when harvested energy is available, reducing the quiescent current draw on the battery to the 200nA required by the shunt charger, thereby extending the life of the battery. The buck-boost powers VOUT only when harvested energy is unavailable.A supercapacitor balancer is also integrated, allowing for increased output storage. Voltage and current settings for both inputs and outputs are programmable via pin-strapped logic inputs. The LTC3331 is available in a 5mm ? 5mm QFN-32 package.Applications Energy Harvesting Solar Powered Systems with Battery Backup Wireless HVAC Sensors and Security Devices Mobile Asset Tracking
