LTC3108IGN-1#PBF

Power Management - Specialized Overview

The LTC3108IGN-1#PBF is a synchronous step-up DC/DC converter and power manager designed for ultra-low voltage energy harvesting applications. It operates with input voltages as low as 20mV, enabling the extraction of energy from sources such as thermoelectric generators, solar cells, and vibration harvesters. The device integrates a high-efficiency boost converter, three LDO regulators, and a supercapacitor charge pump to manage stored energy. It features an integrated MPPT controller to maximize harvested power and includes programmable undervoltage lockout thresholds. The component is housed in a 16-lead SSOP package and supports operation across industrial temperature ranges.

Power Management - Specialized Procurement Notes

Verify the specific suffix IGN-1 against the manufacturer's current datasheet to confirm pinout compatibility and thermal specifications. Ensure that the required input voltage range aligns with the intended energy source characteristics before integration. Cross-reference the package type and operating temperature grade with the design requirements to avoid supply chain mismatches.

Power Management - Specialized Selection Notes

Select this component when the available energy source provides extremely low initial voltages below standard regulator thresholds. It is suitable for designs requiring integrated power management without external MPPT controllers. Consider the output current capabilities and the need for supercapacitor support when sizing the storage element. Evaluate the trade-off between conversion efficiency and quiescent current based on the duty cycle of the target application.

Power Management - Specialized Part Context

This part belongs to Analog Devices' family of ultra-low voltage power management ICs specifically engineered for energy harvesting. It complements other PMIC solutions by offering a complete subsystem for converting ambient energy into usable power. The integration of MPPT and storage management reduces the bill of materials and board space compared to discrete solutions.

Power Management - Specialized Replacement Considerations

Direct substitutes include the LTC3108IGN-PBF and LTC3108EDE-1#PBF, which share similar functionality but may differ in package type or temperature rating. Verify electrical parameters and pin configurations before substitution.
