IS31LT3172-GRLS2-TR

Overview

The IS31LT3172-GRLS2-TR is a linear LED driver IC from Lumissil Microsystems, designed for constant current LED applications. It features a single output capable of delivering up to 200mA with an output voltage rating of 42V. The device supports PWM dimming and operates within a temperature range of -40°C to +125°C. Packaged in an 8-SOP-EP (SOIC) with an exposed pad, it requires a minimum supply voltage of 5V and includes internal switching capabilities.

Feature Summary

Linear constant current regulation with integrated power MOSFET
Supports PWM dimming control for brightness adjustment
Includes internal protection mechanisms for extended operational life

Applications

General lighting systems
Commercial illumination fixtures
Residential LED lighting solutions

Procurement Notes

Verify the specific suffix GRLS2 against the manufacturer's latest datasheet to ensure compatibility with required packaging and tape-and-reel specifications. Confirm that the 8-SOP-EP package dimensions align with your PCB footprint requirements. Check for any recent product change notices or end-of-life announcements, as this component may have availability constraints.

Selection Notes

Select this component for designs requiring simple linear regulation with PWM dimming capability. Ensure the input voltage exceeds the minimum 5V requirement and that the thermal design accommodates the exposed pad for heat dissipation. Verify that the 42V output voltage limit meets the LED string configuration needs without exceeding the device's maximum ratings.

Part Context

This part belongs to the IS31LT31xx series of high-brightness LED drivers from Lumissil Microsystems. These devices are part of a broader portfolio addressing general lighting applications with monolithic-based solutions. The series emphasizes flexibility in design and built-in protections for reliable operation in commercial and residential markets.

Replacement Considerations

The IS31LT3173 is a related variant within the same family. Verify pinout and electrical parameter compatibility before substitution. No other direct public substitutes are confirmed.
