LT3967EFE#TRPBF

LED Driver IC Overview

The LT3967EFE#TRPBF is a high-efficiency, synchronous step-down DC/DC converter from Analog Devices. It operates with an input voltage range of 2.7V to 36V and delivers up to 5A output current. The device integrates a 1.2MHz switching frequency for compact passive component selection. Key electrical parameters include a typical efficiency of 94% at 5V output and a quiescent current of 180µA. It features adjustable soft-start and frequency synchronization capabilities within a thermally enhanced 28-lead QFN package.

LED Driver IC Feature Summary

• Integrated synchronous rectification for high efficiency across load ranges
• Wide input voltage capability supporting various power bus architectures
• Frequency synchronization pin allows alignment with external clocks to reduce EMI

LED Driver IC Applications

• Industrial automation control systems
• Point-of-load regulation for FPGA and ASIC cores
• Battery-powered instrumentation requiring wide input range

LED Driver IC Procurement Notes

Verify the suffix #TRPBF indicates tape-and-reel packaging and lead-free compliance. Confirm the EFE package variant matches thermal requirements. Cross-reference the manufacturer's latest datasheet revision to ensure parameter consistency before finalizing procurement specifications.

LED Driver IC Selection Notes

Select this component when input voltages vary significantly between 2.7V and 36V. Consider the 1.2MHz fixed frequency for balancing size and efficiency. Evaluate thermal performance in the 28-lead QFN package against PCB copper area constraints. Ensure output current demands do not exceed the 5A continuous limit under worst-case thermal conditions.

LED Driver IC Part Context

This part belongs to the LT3967 family of high-voltage step-down converters. It shares architectural similarities with other LDO and buck regulators but distinguishes itself through its specific wide-input range and integrated power switches. It serves as a direct replacement for older discrete solutions or lower-performance buck controllers in space-constrained designs.

LED Driver IC Replacement Considerations

Publicly confirmed substitutes include the LT3967EFE#PBF for tray packaging variants. Verify pinout compatibility and thermal pad dimensions when transitioning between package styles. Check updated datasheets for any minor parameter shifts in newer revisions.
