LTC3210EUD#PBF

LED Driver IC Overview

The LTC3210EUD#PBF is a low-noise charge pump DC/DC converter designed for driving multiple LEDs. It features five outputs: four 25mA channels and one 400mA channel, operating within a 2.9V to 4.5V supply range. The device utilizes an 800kHz switching frequency and integrates internal switches in a 16-lead QFN package.

LED Driver IC Feature Summary

• Integrates four low-current main LED drivers and one high-current camera LED driver
• Employs a switched capacitor topology with automatic mode switching for efficiency optimization
• Includes internal soft-start circuitry to limit inrush current during startup
• Provides linear brightness control via a digital-to-analog converter interface

LED Driver IC Applications

• Multi-LED lighting power supplies for cellular phones
• Digital still camera (DSC) illumination systems
• Personal Digital Assistant (PDA) backlighting

LED Driver IC Procurement Notes

Verify component status as the base part may be obsolete or discontinued. Confirm availability of specific suffix variants such as EUD-1, EUD-2, or EUD-3 which denote different output configurations. Ensure replacement parts meet identical electrical specifications and pinout compatibility before integration into existing designs.

LED Driver IC Selection Notes

Select this component for applications requiring independent current regulation for main display and camera flash LEDs. The design supports operation from a single lithium-ion cell. Consider the 16-QFN package constraints for thermal management and PCB layout requirements associated with high-frequency charge pump circuits.

LED Driver IC Part Context

This device belongs to the LTC3210 family of LED drivers manufactured by Analog Devices Inc. The family includes variants like LTC3210-1, LTC3210-2, and LTC3210-3, which differ primarily in output configuration and control logic. The EUD suffix indicates a specific temperature grade and package type within this product line.

LED Driver IC Replacement Considerations

LTC3210EUD-1#PBF is listed as a similar alternative. Verify if the specific output configuration matches the system requirements, as suffixes indicate functional differences within the series.
