IS31FL3248-QFLS4-TR

Overview

The IS31FL3248-QFLS4-TR is a 48-channel LED driver IC featuring 16-bit PWM brightness control per channel. It operates within a supply voltage range of 2.7V to 5.5V and delivers a constant current of 33.6mA per output. The device utilizes a QFN-64 package with dimensions of 8mm x 8mm. It supports linear constant current dimming and includes open LED protection features for reliable operation in matrix LED applications.

Feature Summary

Provides 16-bit PWM brightness control for high-quality and accurate adjustments
Delivers linear constant current dimming at 33.6mA per channel
Integrates open LED protection for enhanced system reliability

Applications

Matrix LED displays
LED lighting systems requiring precise dimming
Industrial LED drivers

Procurement Notes

Verify the specific suffix QFLS4-TR against the manufacturer's latest datasheet to confirm package type, tape and reel specifications, and environmental compliance status. Ensure compatibility with the target PCB footprint and thermal requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring independent 16-bit PWM control for up to 48 LEDs. It is suitable for applications needing constant current outputs of 33.6mA. Consider the QFN-64 package constraints and the 2.7V to 5.5V operating voltage range during schematic design.

Part Context

This part belongs to Lumissil's IS31FL3x series of industrial LED drivers. These components are designed for wide-range LED support and incorporate EMI noise reduction technology. The series targets high-performance lighting and display applications requiring robust driver integration.

Replacement Considerations

Check for direct substitutes within the IS31FL3x family that match the 48-channel count and QFN-64 package. Verify pin-to-pin compatibility and electrical parameter alignment before considering alternative part numbers.
