DC2048A

DC2048A demonstration circuit is a nano power buckboost DC/DC with energy harvesting battery life extender featuring the LTC®3330. The LTC3330 integrates a high voltage energy harvesting power supply plus a DC/DC converter powered by a primary cell battery to create a single output supply for alternative energy applications. The energy harvesting power supply, consisting of an integrated low-loss full-wave bridge with a high voltage buck converter, harvests energy from piezoelectric, solar or magnetic sources. The primary cell input powers buck-boost converter capable of operating down to 1.8V at its input. Either DC/DC converter can deliver energy to single output. The buck operates when harvested energy is available, reducing quiescent current drawn on battery to essentially zero. The buck-boost takes over when harvested energy goes away. A low noise LDO post regulator and supercapacitor balancer are also integrated, accommodating wide range of output storage configurations.
