IS31LT3170-STLS4-TR

Overview

The IS31LT3170-STLS4-TR is a linear LED driver IC from Lumissil Microsystems, housed in an SOT-23-6 surface-mount package. It provides a single output channel with a maximum current of 150mA and supports a supply voltage range of 2.5V to 5.5V. The device features PWM dimming capability and includes an internal switch, allowing for a 42V output voltage. Designed for operation within a temperature range of -40°C to 125°C, it integrates protections for extended-life operation in lighting applications.

Feature Summary

Integrates an internal power MOSFET switch to simplify circuit design
Supports high-resolution PWM dimming for precise brightness control
Provides built-in protection mechanisms for reliable long-term operation

Applications

General commercial lighting fixtures
Residential LED illumination systems
Automotive interior lighting components

Procurement Notes

Verify the specific suffix STLS4-TR against the manufacturer's latest datasheet to confirm pinout and thermal characteristics. Ensure the design accommodates the linear topology's heat dissipation requirements. Confirm RoHS compliance status through official documentation before finalizing procurement specifications.

Selection Notes

Select this component for low-channel count designs requiring integrated switching capabilities. The linear architecture suits applications where input-output voltage differentials are manageable. Evaluate thermal performance under maximum load conditions to ensure the SOT-23-6 package meets the system's thermal constraints.

Part Context

This part belongs to the Lumissil HBLED Drivers portfolio, which addresses general lighting markets. The series offers both monolithic-based solutions with integrated power MOSFETs and controller-based options. This specific model represents the monolithic approach, combining driver logic and power switching in a compact form factor.

Replacement Considerations

The IS31LT3178-STLS4-TR is listed as a manufacturer-recommended replacement. Verify functional equivalence regarding current rating and interface compatibility before substitution.
