LT3466EFE#PBF

LED Driver IC Overview

The LT3466EFE#PBF is a dual white LED step-up converter featuring an integrated Schottky diode, manufactured by Analog Devices Inc. in a 10-lead EFN package. It operates from a 2.7V to 24V input range with a 2MHz switching frequency. The device provides two independent current-regulated outputs capable of driving up to 300mA each, supporting series or parallel LED configurations. It includes programmable dimming via PWM and analog control, thermal regulation, and open/short LED protection for reliable operation.

LED Driver IC Feature Summary

• Integrates high-efficiency boost converter with internal Schottky diode
• Dual independent constant current outputs for flexible LED topologies
• Supports wide input voltage range suitable for single-cell lithium applications
• Includes comprehensive protection features against thermal overload and faults

LED Driver IC Applications

• White LED illumination drivers
• Backlighting for portable devices
• General lighting systems requiring dual-channel control

LED Driver IC Procurement Notes

Verify the specific suffix #PBF indicates the tube package variant when ordering. Confirm that the component matches the required 10-lead EFN footprint for PCB layout compatibility. Ensure supply chain sources provide valid manufacturer traceability documentation. Cross-reference the full part number against official Analog Devices catalogs to avoid confusion with tape-and-reel versions.

LED Driver IC Selection Notes

Select this component for designs requiring dual-channel LED drive from a single boost stage. It is suitable for applications needing precise current regulation without external sense resistors for each channel. Consider the 2MHz frequency for smaller passive component sizes. Evaluate thermal performance requirements given the integrated power switch and diode within the compact package.

LED Driver IC Part Context

This part belongs to the LT3466 family of dual white LED drivers. It shares architectural similarities with other Analog Devices LED controllers but is distinct in its integrated Schottky diode feature. The EFE suffix denotes the specific 10-lead EFN package type used for space-constrained designs.

LED Driver IC Replacement Considerations

LT3466EDD-1#PBF offers similar functionality in a DFN-10 package.
