IS31FL3208A-QFLS4-TR

Overview

The IS31FL3208A-QFLS4-TR is an 18-channel FxLED driver IC manufactured by Lumissil Microsystems. It operates within a supply voltage range of 2.7 V to 5.5 V and supports adjustable output voltages. The device features independent PWM controllers with a working frequency of 23 kHz and delivers up to 38 mA per channel. It utilizes Boost and Buck topologies for efficient power management. The component is housed in a QFN-28 package measuring 4.0 mm x 4.0 mm, suitable for surface mount installation. It functions reliably across an operating temperature range from -40°C to +125°C.

Feature Summary

Provides accurate, programmable current control for LEDs up to 38mA per channel
Supports up to 18 independent PWM controller outputs
Integrates Boost and Buck topology for flexible LED driving

Applications

LED display systems requiring precise channel control
Industrial FXLED lighting applications
General-purpose LED driver circuits

Procurement Notes

Verify the specific suffix QFLS4 against the manufacturer's latest datasheet to confirm package dimensions and thermal characteristics. Ensure compatibility with I2C or PWM interface requirements if applicable. Check moisture sensitivity level (MSL) ratings for proper storage and reflow soldering profiles. Confirm RoHS compliance status with the supplier prior to final procurement decisions.

Selection Notes

Select this component when designing systems requiring high channel density in a compact QFN-28 footprint. Consider the 38 mA per channel limit for LED brightness requirements. Evaluate the 23 kHz PWM frequency against audible noise constraints. Compare against the IS31FL3209 series if linear regulation or different current scaling methods are preferred over the switching topology offered here.

Part Context

This part belongs to the IS31FL3208A series of LED lighting drivers from Lumissil Microsystems. These components are designed for industrial applications supporting a wide range of LED configurations. The series emphasizes EMI noise reduction technology and robust performance in demanding environments, distinguishing it from standard consumer-grade LED drivers.
