IS31FL3236-QFLS2-TR

Overview

The IS31FL3236-QFLS2-TR is a 36-channel LED driver IC manufactured by Lumissil Microsystems. It features independent PWM control for each channel and supports Boost and Buck topologies. The device operates within an input voltage range of 2.7 V to 5.5 V, with a maximum output current of 38 mA per channel. It utilizes I2C control and functions at a working frequency of 400 kHz. Packaged in a QFN-44 (5x5 mm) format, it is designed for industrial applications with an operating temperature range from -40°C to +85°C.

Feature Summary

Integrates 36 constant current channels with independent PWM dimming control
Supports both Boost and Buck converter topologies for flexible LED driving
Enables digital configuration via standard I2C communication interface

Applications

Industrial LED lighting systems
Automotive interior and exterior illumination
General-purpose LED matrix displays

Procurement Notes

Verify the specific suffix against official Lumissil documentation to confirm pinout and electrical characteristics. Ensure the component meets the required industrial temperature range specifications for your target application environment before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring high channel density with individual PWM control. Consider the QFN-44 package constraints and thermal dissipation requirements associated with the 38 mA output capability per channel during the layout phase.

Part Context

This part belongs to the IS31FL3236A series of LED lighting drivers. It serves as a specialized solution for applications demanding multiple independently controlled LED outputs within a compact footprint, distinguishing itself through integrated power stage support and digital interface capabilities.

Replacement Considerations

The IS31FL3235-QFLS2-TR is a related variant within the same family, though it offers different output configurations and packaging options. Verify compatibility regarding channel count and physical dimensions before substitution.
