LTC3110IUF#PBF

Battery Chargers Overview

The LTC3110IUF#PBF is a bidirectional buck-boost DC/DC regulator manufactured by Analog Devices Inc. It integrates a capacitor charger and balancer, designed for energy harvesting and backup applications. The device supports a wide input voltage range from 0.1V to 5.5V for capacitors or batteries, while providing a regulated system backup voltage between 1.8V and 5.25V. It delivers up to 2A of current in both charging and discharging modes.

Battery Chargers Feature Summary

• Bidirectional buck-boost topology enabling seamless transition between charging storage elements and powering the load
• Integrated supercapacitor charger with automatic balancing capabilities for multi-cell configurations
• Wide operating input voltage range accommodating low-voltage energy harvesters and depleted backup sources

Battery Chargers Applications

• Supercapacitor-based power backup systems
• Energy harvesting circuits requiring voltage regulation from ultra-low voltage sources
• Battery management systems utilizing bidirectional charge transfer

Battery Chargers Procurement Notes

Verify the specific suffix #PBF indicates lead-free RoHS compliance when ordering. Confirm the package type matches the design requirements, as this component utilizes a 24-pin QFN EP package. Ensure that the thermal pad connection is properly addressed in the PCB layout to maintain optimal performance and reliability during operation.

Battery Chargers Selection Notes

Select this component when designing systems that require managing supercapacitors or batteries with very low initial voltages. It is suitable for applications needing a regulated output despite significant fluctuations in the source voltage. Consider the bidirectional nature if the system must recharge the storage element from the main supply while maintaining backup capability.

Battery Chargers Part Context

This part belongs to the LTC3110 family of switching regulators from Analog Devices. It is specifically engineered for interfacing with energy storage devices like supercapacitors. The IUF#PBF designation identifies the industrial temperature grade version in a 24-lead QFN package, distinguishing it from other variants in the series.

Battery Chargers Replacement Considerations

Direct replacements are not explicitly listed in the provided documentation. Engineers should evaluate other Analog Devices bidirectional buck-boost controllers or integrated charger ICs based on similar voltage ranges and current capabilities.
