IS31FL3205-QFLS4-TR

Overview

The IS31FL3205-QFLS4-TR is a 12-channel linear LED driver IC manufactured by Lumissil Microsystems. It features selectable PWM frequency and operates within an input voltage range of 2.7 V to 5.5 V. The device provides constant current output with a maximum sink current of 38 mA per channel. It is housed in a QFN-20 package measuring 3.0 mm x 3.0 mm. The component supports surface mount technology and functions across a temperature range of -40°C to +125°C.

Feature Summary

Provides 12 independent constant current outputs for precise LED control
Supports selectable PWM dimming frequencies for flexible lighting applications
Integrates linear regulation for efficient current sinking

Applications

LED backlighting systems
General LED illumination circuits
Portable electronic display drivers

Procurement Notes

Verify the complete part number including the suffix to ensure correct packaging and specifications. Confirm RoHS compliance status through official documentation before integration. Check for specific manufacturing lot requirements if applicable to your production standards. Ensure compatibility with your PCB footprint design for the QFN-20 package.

Selection Notes

Select this component when a high channel count is required in a compact form factor. The 38 mA output capability suits standard indicator and low-power lighting LEDs. Consider the thermal performance of the QFN-20 package for your enclosure design. Verify that the selected PWM frequency meets the flicker-free requirements of your application.

Part Context

This device belongs to the IS31FL32xx series of LED lighting drivers from Lumissil. These components are designed for applications requiring multiple channels with individual current control. The series emphasizes small footprint solutions for modern consumer electronics and automotive interfaces.
