LT3761IMSE#TRPBF

LED Driver IC Overview

The LT3761IMSE#TRPBF is a DC/DC controller designed to operate as a constant-current source and constant-voltage regulator. It features a programmable internal PWM dimming signal, making it suitable for driving high current LEDs. The device supports multiple converter topologies including flyback, SEPIC, step-down (buck), and step-up (boost). It operates with an input voltage range of 8V to 60V and can deliver output currents up to 1.67A depending on the configuration.

LED Driver IC Feature Summary

• Supports multiple LED driver topologies including boost, buck, SEPIC, and flyback
• Features a programmable internal PWM dimming signal for brightness control
• Designed for constant-current and constant-voltage regulation applications

LED Driver IC Applications

• High current LED driving

• General purpose DC/DC conversion using boost or buck topologies

LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the operating temperature range of -40°C to 125°C matches your environmental requirements. Ensure the 16-MSOP-EP package footprint aligns with your PCB design constraints before finalizing procurement.

LED Driver IC Selection Notes

Select this component when a versatile DC/DC controller supporting multiple topologies is required. It is appropriate for designs needing integrated PWM dimming capabilities without external generation circuits. Consider the 8V to 60V input range and the need for constant-current regulation in LED applications.

LED Driver IC Part Context

This part belongs to the LT3761 family from Analog Devices Inc., which includes variants like the LT3761-1. These controllers are engineered for flexible power management solutions, particularly in lighting applications where precise current regulation and dimming are critical. The IMSE package denotes a 16-lead MSOP with exposed pad.

LED Driver IC Replacement Considerations

Check for direct pin-compatible alternatives within the LT3761 series such as LT3761IMSE#PBF for non-reel packaging. Verify if other Analog Devices LED drivers meet the specific topology and current requirements if this exact part is unavailable.
