IS31LT3360-SDLS3-TR

Overview

The IS31LT3360-SDLS3-TR is a monolithic step-down (buck) LED driver IC manufactured by Lumissil Microsystems. It integrates a 1.2A internal power switch and operates within a 6V to 40V input voltage range, supporting output voltages up to 40V. The device features a fixed 1MHz switching frequency and supports both analog and PWM dimming methods for precise light control. Designed for automotive-grade applications, it functions reliably across a temperature range of -40°C to 105°C. The component is housed in a compact SOT-89-5 surface-mount package.

Feature Summary

Integrates a high-current 1.2A internal power switch for efficient buck conversion
Supports flexible illumination control through combined analog and PWM dimming capabilities
Engineered with automotive-grade reliability standards for harsh operating environments
Utilizes a compact SOT-89-5 package to minimize board space requirements

Applications

Automotive exterior lighting systems
General commercial and residential LED lighting
Industrial equipment status indicators

Procurement Notes

Verify the specific suffix SDLS3 against the official Lumissil datasheet to confirm pinout and thermal characteristics. Confirm RoHS3 compliance and REACH status prior to integration. Check current lifecycle status as distribution channels may indicate discontinuation or limited availability. Ensure the SOT-89-5 footprint matches the target PCB design constraints.

Selection Notes

Select this component for designs requiring a single-channel, high-current buck topology with integrated switching elements. It is suitable for applications needing wide input voltage compatibility and robust thermal performance. Consider the SOT-89-5 package size when evaluating spatial constraints. Verify that the required dimming interface aligns with the supported analog and PWM modes.
