LT3466EDD#PBF

LED Driver IC Overview

The LT3466EDD#PBF is a dual full-function white LED step-up converter manufactured by Analog Devices Inc. It operates from an input voltage range of 2.7 V to 24 V and provides two independent boost outputs with a maximum output current of 400 mA per channel. The device utilizes a fixed 1 MHz switching frequency and employs current-mode control for stable regulation. Housed in a compact 10-lead DFN (3 mm x 3 mm) package, it integrates internal Schottky diodes and supports PWM dimming. The component functions within a temperature range of -40°C to +85°C.

LED Driver IC Feature Summary

• Dual independent boost converters designed specifically for driving white LED strings
• Integrated internal Schottky diodes eliminate the need for external rectifiers
• Supports PWM dimming for precise brightness control applications
• Current-mode control architecture ensures stable line and load regulation

LED Driver IC Applications

• Backlighting for mobile phone displays
• Backlighting for digital camera screens
• Backlighting for PDA devices
• Automotive electronic display illumination

LED Driver IC Procurement Notes

Verify the specific suffix #PBF indicates RoHS compliance when sourcing. Confirm the DFN-10 package dimensions match the PCB footprint requirements. Ensure the operating environment stays within the specified -40°C to +85°C temperature range. Check for availability constraints as supply status may vary by region. Validate that the 24 V maximum input voltage aligns with the system power source.

LED Driver IC Selection Notes

Select this component for designs requiring dual independent LED channels from a single wide-input voltage source. The integrated Schottky diodes reduce external component count compared to solutions requiring discrete rectifiers. The 1 MHz switching frequency allows for smaller passive components than lower-frequency alternatives. Verify that the 400 mA output current capability meets the total LED string requirements for both channels simultaneously.

LED Driver IC Part Context

This part belongs to the LT3466 series of dual LED drivers. It is functionally similar to the LT3466EDD but includes the #PBF suffix denoting lead-free and RoHS-compliant manufacturing. The device serves as a specialized power management IC for portable electronics requiring efficient high-voltage LED drive from low-voltage batteries.

LED Driver IC Replacement Considerations

LT3466EDD#TRPBF offers identical electrical performance in a tape-and-reel packaging format suitable for automated assembly processes.
