Overview
The IS31FL3236A-QFLS2-TR is a 36-channel LED lighting driver IC manufactured by Lumissil Microsystems. It features an integrated boost and buck topology with adjustable output voltage, supporting a supply voltage range of 2.7 V to 5.5 V. The device delivers up to 38 mA per channel and operates at a frequency of 400 kHz. Controlled via I2C interface, it functions within temperatures from -40°C to +85°C in a QFN-44 package.
Feature Summary
- Integrates boost and buck topologies for flexible LED drive configurations
- Provides independent constant current control for 36 channels
- Utilizes I2C interface for digital dimming and configuration
Applications
- Automotive interior ambient lighting systems
- Dashboard and instrument cluster backlighting
- High-density LED matrix displays
Procurement Notes
Verify the specific suffix (QFLS2) against the official datasheet to confirm temperature grade and packaging specifications. Ensure compatibility with I2C bus voltage levels and check for moisture sensitivity handling requirements during storage and assembly processes.
Selection Notes
Select this component when high channel count and precise current regulation are required. The integrated power stage simplifies design compared to discrete solutions. Verify that the thermal performance of the QFN-44 package meets the application's heat dissipation needs under maximum load conditions.
Part Context
This part belongs to the IS31FL3236A series, designed for multi-channel LED applications. It represents a specialized solution for complex lighting architectures requiring individual channel control without external microcontrollers for basic operation.
Replacement Considerations
The IS31FL3236A-QFLS4-TR offers similar functionality but utilizes a different package type. Evaluate pinout compatibility and thermal characteristics before substituting.
