Description

The LTC3106 is a highly integrated, ultralow voltage buck-boost DC/DC converter with automatic PowerPath management optimized for multisource, low power systems. At no load, the LTC3106 draws only 1.6μA while creating an output voltage up to 5V from either input source.If the primary power source is unavailable, the LTC3106 seamlessly switches to the backup power source. The LTC3106 is compatible with either rechargeable or primary cell batteries and can trickle charge a backup battery whenever there is an energy surplus available. Optional maximum power point control ensures power transfer is optimized between power source and load. The output voltage and backup voltage, VSTORE, are programmed digitally, reducing the required number of external components. Zero power Shelf Mode ensures that the backup battery will remain charged if left connected to the LTC3106 for an extended time.Additional features include an accurate turn-on voltage, a power good indicator for VOUT, a user selectable 100mA peak current limit setting for lower power applications, thermal shutdown as well as user selectable backup power and output voltages.ApplicationsWireless Sensor NetworksHome or Office Building AutomationEnergy HarvestingRemote Sensors
