Product Details
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 full-wave bridge rectifier and a high voltage buck converter, harvests energy from piezoelectric, solar, or magnetic sources. The primary cell input powers a buck-boost converter capable of operation down to 1.8V at its input. 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 essentially zero, thereby extending the life of the battery. The buck-boost powers VOUT only when harvested energy goes away.
A low noise LDO post regulator and a supercapacitor balancer are also integrated, accommodating a wide range of output storage configurations. Voltage and current settings for both inputs and outputs are programmable via pin-strapped logic inputs. The LTC3330 is available in a 5mm × 5mm QFN-32 package.
