IS31FL3209-QFLS4-TR

Overview

The IS31FL3209-QFLS4-TR is an 18-channel linear LED driver IC manufactured by Lumissil Microsystems. It operates within a supply voltage range of 2.7V to 5.5V and delivers up to 76mA per channel. The device supports I2C control for dimming and features Buck and Boost topologies. It is housed in a 28-WFQFN package with dimensions of 4mm x 4mm. The component functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

Supports 18 independent constant current channels for uniform LED illumination
Enables precise brightness control via I2C interface communication
Integrates Buck and Boost switching topologies for flexible power management

Applications

General-purpose LED lighting systems
Automotive interior ambient lighting
Industrial indicator arrays

Procurement Notes

Verify the specific suffix QFLS4 against the manufacturer's latest datasheet to confirm pinout and thermal pad configuration. Ensure the ordering quantity aligns with standard reel sizes, typically 2,500 units. Confirm RoHS3 compliance status if required by your assembly specifications before finalizing procurement orders.

Selection Notes

Select this component when an 18-channel solution with high current capability is required. The linear topology simplifies design but requires adequate thermal management. Verify that the host microcontroller supports the necessary I2C clock speed and address configuration for reliable system integration.

Part Context

This part belongs to the IS31FL3209 series from Lumissil Microsystems. It is designed for applications requiring multiple independently controlled LED outputs. The QFLS4 suffix indicates the specific package variant and tape-and-reel packaging format used for automated surface-mount assembly processes.

Replacement Considerations

Check for direct substitutes within the IS31FL32xx family. Verify pin compatibility and electrical parameters before swapping. No confirmed public substitute part numbers are available in the provided documentation.
