IS31FL3726A-QFLS4-TR

Overview

The IS31FL3726A-QFLS4-TR is a linear LED driver IC manufactured by Lumissil Microsystems, housed in a 24-QFN (4x4) package. It features 16 outputs with a shift register topology and supports PWM dimming. The device operates on a supply voltage range of 3.3V to 5.5V, delivering up to 60mA per channel with an internal switch. It functions within a temperature range of -40°C to 85°C and utilizes a 20MHz frequency interface.

Feature Summary

Integrates a shift register topology for efficient serial data handling and output control.
Supports PWM dimming functionality for precise brightness adjustment across channels.
Features internal switches to manage load connections without external components.

Applications

LED backlighting systems
General LED lighting drivers

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm the specific suffix QFLS4 matches design requirements. Check for end-of-life status as previous variants may be discontinued. Ensure RoHS3 compliance aligns with environmental regulations. Validate MSL level 3 handling procedures during assembly.

Selection Notes

Select this component for designs requiring 16-channel linear drive with PWM capability. Ensure the 24-QFN footprint fits the PCB layout constraints. Verify that the 60mA output current meets LED string requirements. Confirm the 3.3V to 5.5V supply range matches the system power architecture.

Part Context

This part belongs to the IS31FL3726 family of LED drivers from Lumissil Microsystems. It serves as a specialized solution for managing multiple LED channels in compact form factors. The series focuses on linear regulation with integrated shift registers for simplified interfacing.

Replacement Considerations

IS31FL3726A-QFLS4-TR is listed as a manufacturer-recommended alternative to the IS31FL3726-QFLS2-TR. Verify pin compatibility and electrical specifications before substitution.
