Overview
The IS31FL3236A-TQLS4-TR is a 36-channel LED lighting driver IC manufactured by Lumissil Microsystems. It operates within an input voltage range of 2.7 V to 5.5 V and supports both Boost and Buck topologies. The device provides constant current output with a maximum output current of 38 mA per channel. It features I2C control interface and selectable clock options. The component is housed in a 48-eTQFP package measuring 7x7 mm. Operating temperatures range from -40°C to +125°C, with a maximum power supply current of 9 mA and a switching frequency of 400 kHz.
Feature Summary
- Supports 36 independent channels for high-density LED matrix applications
- Integrates adjustable boost and buck converters for flexible LED drive configurations
- Utilizes I2C interface for digital control and dimming management
Applications
- LED display panels requiring multi-channel constant current drive
- Automotive interior lighting systems
- Industrial FXLED drivers
Procurement Notes
Verify the specific suffix (TQLS4) against official Lumissil documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 48-eTQFP form factor. Cross-reference electrical specifications with system requirements before integration. Confirm availability status through authorized distributors as lead times may vary.
Selection Notes
Select this component when a high channel count is required in a compact footprint. The integrated power stage eliminates external inductors for certain configurations. Verify that the I2C address configuration meets system bus constraints. Consider thermal performance under maximum load conditions given the dense packaging.
Part Context
This part belongs to the IS31FL3236 series of LED lighting drivers designed for industrial and automotive applications. The series emphasizes EMI noise reduction and wide LED support ranges. It serves as a specialized solution for complex LED matrices where precise current regulation and digital control are critical.
Replacement Considerations
Check for direct substitutes within the IS31FL3236 family such as IS31FL3236A-QFLS4-TR or IS31FL3236-TQLS2-TR. Verify pinout compatibility and electrical parameter equivalence before substitution. Consult official datasheets for any functional differences between variants.
