LTC3588-2 Nanopower Energy Harvesting Power Supply with 14V Minimum V IN FEATURES DESCRIPTION n 1500nA Input Quiescent Current (Output in The LTC 3588-2 integrates a low-loss full-wave bridge Regulation No Load, V = 18V) rectifier with a high efficiency buck converter to form a IN n 830nA Input Quiescent Current in UVLO, V = 12V complete energy harvesting solution optimized for high IN n 14V to 20V Input Operating Range output impedance energy sources such as piezoelectric, n Integrated Low-Loss Full-Wave Bridge Rectifier solar, or magnetic transducers. n 16V UVLO Improves Power Utilization from High An ultralow quiescent current undervoltage lockout (UVLO) Voltage Current Limited Inputs mode with a 16V rising threshold enables efficient energy n Up to 100mA of Output Current extraction from sources with high open circuit voltages. n High Efficiency Integrated Hysteretic Buck DC/DC This energy is transferred from the input capacitor to the n Selectable Output Voltages: 3.45V, 4.1V, 4.5V, 5.0V output via a high efficiency synchronous buck regulator. n Input Protective Shunt Up to 25mA Pull-Down at The 16V UVLO threshold also allows for input to output V 20V IN current multiplication through the buck regulator. The n Available in 10-Lead MSE and 3mm 3mm DFN buck features a sleep state that minimizes both input and Packages output quiescent currents while in regulation. Four output voltages of 3.45V, 4.1V, 4.5V and 5.0V are APPLICATIONS pin selectable with up to 100mA of continuous output n Piezoelectric Energy Harvesting batteries as well as current, and suit Li-Ion and LiFePO 4 n Electro-Mechanical Energy Harvesting supercapacitors. An input protective shunt set at 20V n Low Power Battery Charging provides overvoltage protection. n Wireless HVAC Sensors L, LT, LTC, LTM, Linear Technology, the Linear logo and Burst Mode are registered trademarks of Linear Technology Corporation.
