Product Overview

The LTC3331EUH#PBF is 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. 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.
  • Dual input, single output DC/DCs with input prioritizer
  • Battery input - Up to 4.2V Buck-Boost DC/DC
  • 10mA Shunt battery charger with programmable float voltages (3.45, 4, 4.1 and 4.2V)
  • Low battery disconnect
  • 950nA at no load Ultra Low quiescent current
  • Integrated supercapacitor balancer
  • Up to 50mA Output current
  • Programmable DC/DC output voltage, buck UVLO and buck-boost peak input current
  • Integrated low-loss full-wave bridge rectifier
  • Input protective shunt - Up to 25mA at VIN >=20V
  • Green product and no Sb/Br
