LT3966JUJ#TRPBF

LED Driver IC Overview

The LT3966JUJ#TRPBF is an I2C programmable monolithic boost LED driver featuring four independent channels. Each channel integrates a 60V current-mode boost converter with a 1.6A DMOS power switch. The device supports input voltages from 3V to 60V and operates at switching frequencies between 300kHz and 4MHz. It offers analog and PWM dimming capabilities, housed in a 40-lead QFN package.

LED Driver IC Feature Summary

• Four independent high-voltage boost channels for flexible LED string configurations
• I2C interface for programmable control of operating parameters
• Integrated 1.6A power switch within each channel
• Supports both analog and pulse-width modulation dimming methods

LED Driver IC Applications

• LED backlighting systems
• High-power LED lighting fixtures
• Industrial illumination applications

LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. Ensure the component matches the 40-QFN physical footprint. Check RoHS compliance status through official documentation before integration into production designs.

LED Driver IC Selection Notes

Select this component for designs requiring four isolated LED strings driven by a single controller. The 60V rating suits high-series LED arrays. Consider thermal management requirements due to integrated power switches. Verify I2C bus compatibility with the host microcontroller for configuration.

LED Driver IC Part Context

This part belongs to the LT3966 family of quad-channel LED drivers. It shares core architecture with variants like LT3966JUJ#PBF, differing primarily in packaging format. The series is designed for high-efficiency, high-voltage LED driving applications requiring precise current regulation.

LED Driver IC Replacement Considerations

LT3966JUJ#PBF is a verified substitute offering identical electrical specifications but in tube packaging instead of tape-and-reel.
