Overview
The IS31FL3242-QFLS4-TR is an LED lighting driver IC manufactured by Lumissil Microsystems. It features a QFN-20 package with dimensions of 3mm x 3mm and operates in surface-mount applications. The device supports linear PWM dimming with an output current of 48mA across 12 outputs, configured as 4 RGB channels. It functions within a supply voltage range of 2.7V to 5.5V and withstands operating temperatures from -40°C to +125°C.
Feature Summary
- Integrates four independent RGB channels for precise color control
- Supports linear pulse-width modulation for smooth brightness adjustment
- Delivers constant current output at 48mA per channel
Applications
- RGB LED matrix displays
- Backlighting systems requiring color mixing
- Compact indicator arrays
Procurement Notes
Verify the specific suffix QFLS4-TR against official Lumissil documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with I2C or hardware control interfaces if applicable. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly to prevent damage during manufacturing processes.
Selection Notes
Select this component when a compact solution for multi-color LED control is required. The 3x3mm QFN-20 footprint suits space-constrained designs. Verify that the 48mA output current meets the forward current requirements of the target LEDs. Consider thermal dissipation capabilities within the small package for high-duty cycle operations.
Part Context
This part belongs to the IS31FL32xx series of LED drivers from Lumissil Microsystems. These devices are designed for general-purpose LED illumination and display applications. The series typically offers integrated current regulation and dimming capabilities in small form factors suitable for portable and consumer electronics.
Replacement Considerations
Check for direct substitutes such as the IS31FL3242A variant if available. Verify pinout compatibility and electrical parameters before substitution. Consult manufacturer notices for obsolescence status.
