IS31FL3235-QFLS2-TR

Overview

The IS31FL3235-QFLS2-TR is a 28-output linear LED driver IC manufactured by Lumissil Microsystems. It features I2C dimming control and supports boost and buck topologies. The device operates within a supply voltage range of 2.7 V to 5.5 V, with an adjustable output voltage and a maximum output current of 23 mA per channel. It functions at a working frequency of 400 kHz and is housed in a QFN-36 package. The component is rated for operation between -40°C and +85°C.

Feature Summary

Provides 28 independent constant current channels for precise LED management
Integrates I2C interface for digital dimming control
Supports both boost and buck converter topologies
Includes internal switching capabilities

Applications

LED backlighting systems
General LED lighting drivers

Procurement Notes

Verify the specific revision suffix, as the datasheet indicates this part number may be marked as Not Recommended for New Designs (NRND). Confirm availability through authorized distributors, noting that lead times and stock levels fluctuate. Ensure the ordering information matches the exact package type and temperature rating required for the target application environment.

Selection Notes

Select this component when a high-channel-count linear driver with I2C control is required. Compare against the IS31FL3235A variant, which offers higher current ratings. Consider the NRND status for long-term production viability. Evaluate thermal performance within the QFN-36 package constraints and ensure the system power supply aligns with the 2.7V to 5.5V operating range.

Part Context

This IC belongs to the IS31FL3235 series from Lumissil Microsystems, designed for multi-channel LED applications. It is distinct from the IS31FL3236 evaluation board and other series members like the IS31FL3218. The product line focuses on integrated solutions for display and lighting control, leveraging I2C communication for efficient system integration.

Replacement Considerations

The IS31FL3235A-QFLS2-TR is a related variant offering 38mA output current. Verify pin compatibility and electrical specifications before substitution. No other direct public substitutes are confirmed.
