Product Overview

The LTC3330IUH#PBF is a Nanopower Buck-boost DC/DC Converter comes with an energy harvesting battery life extender. It 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. 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 super capacitor balancer are also integrated, accommodating a wide range of output storage configurations.
  • Zero battery IQ when energy harvesting source is available
  • 750nA at No-load ultralow quiescent current
  • Low noise LDO post regulator
  • Integrated super capacitor balancer
  • Up to 50mA of output current
  • Integrated low loss full-wave bridge rectifier
