IS31FL3728-QFLS2-TR

Overview

The IS31FL3728-QFLS2-TR is an LED display driver manufactured by Lumissil Microsystems, housed in a 24-VFQFN package. It features 16 linear outputs with I2C control for dimming. The device operates on a supply voltage ranging from 2.7V to 5.5V and draws a maximum power current of 5 mA. It supports PWM dimming and functions within a temperature range of -40°C to +85°C.

Feature Summary

Integrates 16 linear output channels for LED driving
Utilizes I2C interface for digital control and configuration
Supports PWM dimming functionality for brightness adjustment

Applications

Backlight applications
LED matrix displays
Audio modulator LED drivers

Procurement Notes

Verify the specific suffix QFLS2 against the manufacturer's official part number guide to ensure correct packaging and tape specifications. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements during storage and handling. Cross-reference the datasheet revision to ensure compatibility with existing design files and ECAD models.

Selection Notes

Select this component when a compact solution with integrated I2C control and 16 linear channels is required. Ensure the system power supply falls within the 2.7V to 5.5V range. Consider the 24-QFN package constraints for PCB layout and thermal management. Verify that the application does not require higher current capabilities than the linear topology provides.

Part Context

This part belongs to the IS31FL3728 series of LED display drivers from Lumissil Microsystems. It is designed for applications requiring precise LED control via a serial interface. The series typically targets portable electronics and display systems where space efficiency and low power consumption are critical design parameters.

Replacement Considerations

IS31FL3726A-QFLS4-TR is listed as a manufacturer-recommended substitute for related parts in the family, though direct pin-to-pin equivalence should be verified against official documentation.
