LT3966EUJ#PBF

LED Driver IC Overview

The LT3966EUJ#PBF is a quad-channel LED driver IC from Analog Devices, designed for high-voltage applications. It integrates a boost DC-DC converter with a 60V power switch and supports input voltages from 3V to 60V. The device delivers up to 1.6A output current per channel and operates at switching frequencies between 300kHz and 4MHz. It features I2C control for configuration without a microcontroller and supports both analog and PWM dimming. Packaged in a 40-pin QFN (6x6mm) with an exposed pad, it functions as a standalone regulator configurable from 20mA to 150mA via external resistors.

LED Driver IC Feature Summary

• Integrates a 60V boost converter with four independent LED channels
• Supports I2C digital interface for configuration and control
• Enables mixed analog and PWM dimming capabilities
• Operates as a standalone driver without requiring a microcontroller

LED Driver IC Applications

• Automotive exterior lighting systems
• High-brightness LED backlighting arrays
• Industrial LED illumination fixtures
• General-purpose high-voltage LED drivers

LED Driver IC Procurement Notes

Verify the specific suffix #PBF confirms lead-free RoHS compliance and tube packaging. Confirm the EUJ package variant matches the required 40-QFN footprint. Check current availability status as supply may be limited or subject to factory order constraints. Ensure the operating temperature range of -40°C to +125°C meets the target environment requirements.

LED Driver IC Selection Notes

Select this component when a single IC must drive multiple high-voltage LEDs efficiently. The integrated boost topology simplifies design by eliminating external inductors for step-up conversion. Choose if I2C programmability reduces board space compared to discrete logic solutions. Verify that the 1.6A per-channel current rating aligns with the total LED string requirements.

LED Driver IC Part Context

This part belongs to the LT3966 series of quad-channel LED drivers. It shares functional similarities with other LT396x family members but is distinct in its specific voltage ratings and pinout configuration. The EUJ designation identifies the specific thermal and mechanical package dimensions used for surface-mount assembly.

LED Driver IC Replacement Considerations
