IS31LT3910-GRLS2-TR

Overview

The IS31LT3910-GRLS2-TR is an LED driver IC manufactured by Lumissil Microsystems. It features a supply current of 640uA and utilizes an 8-pin SOP package with tape and reel (TR) packaging. The device functions as a DC-DC controller, specifically configured for step-down (Buck) topology applications. It supports both analog and PWM dimming methods to control LED output intensity.

Feature Summary

• Supports step-down (Buck) DC-DC conversion topology
• Enables precise LED brightness control via analog and PWM dimming interfaces

Applications

• LED lighting systems requiring buck converter topologies
• General-purpose LED driver circuits

Procurement Notes

Verify the specific ordering suffix GRLS2-TR against official Lumissil documentation to confirm package type and reel specifications. Ensure compatibility with system voltage requirements for the Buck topology. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current availability status before finalizing procurement orders.

Selection Notes

Select this component when a low quiescent current solution is required for LED driving applications. The integrated Buck controller simplifies design by reducing external component count compared to discrete solutions. Consider the 8-SOP package constraints for PCB layout and thermal management in compact enclosures.

Part Context

This part belongs to the Lumissil IS31LT series of LED drivers. It is distinct from evaluation boards like the IS31LT3352-V1GRLS2-EBMR16, which are development tools rather than end-use components. The series focuses on providing efficient power management solutions for various lighting applications.
