IS31FL3296-QFLS4-TR

Overview

The IS31FL3296-QFLS4-TR is a linear LED driver IC featuring six constant current outputs. It supports I2C and PWM dimming interfaces with an output current of 40 mA per channel. The device operates within a supply voltage range of 2.7 V to 5.5 V and functions at a frequency of 440 Hz. Packaged in a QFN-20 (3mm x 3mm) format, it withstands temperatures from -40°C to +125°C.

Feature Summary

• Integrates I2C and PWM dimming capabilities for flexible control
• Provides six independent constant current outputs
• Includes short circuit and thermal protection mechanisms

Applications

• RGB LED matrix displays
• General LED lighting systems
• Portable electronic devices requiring compact drivers

Procurement Notes

Verify the specific suffix QFLS4 against official Lumissil documentation to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with I2C bus requirements and check moisture sensitivity level handling procedures during assembly. Confirm RoHS3 compliance status through current datasheets before finalizing procurement orders.

Selection Notes

Select this component when a compact solution for driving multiple LEDs is required. The QFN-20 package suits space-constrained designs. Verify that the 40 mA output current meets load requirements and that the 2.7 V to 5.5 V input range aligns with system power rails. Consider thermal management needs given the linear topology.
