LT3756IMSE-1#TRPBF

LED Driver IC Overview

The LT3756IMSE-1#TRPBF is a single-channel LED lighting driver IC from Analog Devices Inc., designed for high-voltage applications. It supports input voltages from 6V to 100V and can drive loads up to 100V output. The device operates with a switching frequency range of 100kHz to 1MHz and features both analog and PWM dimming capabilities. Packaged in a 16-lead MSOP with exposed pad, it includes open LED protection and supports multiple topologies including boost, buck, flyback, and SEPIC configurations.

LED Driver IC Feature Summary

• Supports flexible DC-DC topologies including boost, buck, flyback, and SEPIC for diverse LED driving requirements
• Enables precise brightness control through integrated analog and pulse-width modulation (PWM) dimming interfaces
• Incorporates hardware-based open LED protection to safeguard the load and controller during fault conditions

LED Driver IC Applications

• General LED lighting systems requiring high voltage headroom
• Automotive exterior lighting applications such as headlights or taillights
• Industrial display backlights and indicator circuits

LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm that the IMSE variant meets the required thermal performance for your enclosure design. Check current availability status as supply may be restricted in certain regions. Ensure compatibility with your PCB footprint for the 16-MSOP-EP package before finalizing procurement.

LED Driver IC Selection Notes

Select this component when designing circuits that require handling input voltages up to 100V without external level shifting. Choose the -1 suffix version if specific pinout or functional variations defined in the datasheet are necessary for your topology. Consider the exposed pad thermal properties for heat dissipation in dense layouts compared to standard packages.

LED Driver IC Part Context

This part belongs to the LT3756 family of high-voltage LED controllers manufactured by Analog Devices Inc. It shares core architecture with variants like the LT3756JMSE-2#PBF but differs in package type and specific electrical characteristics. The series is widely used in automotive and industrial sectors where robust high-side driving and wide input ranges are critical.
