TLC5928RGER

Overview

The TLC5928RGER is an LED lighting driver IC from Texas Instruments featuring a boost topology and sixteen constant current outputs. It operates within a supply voltage range of 3 V to 5.5 V, delivering up to 35 mA per channel with a maximum output voltage of 17 V. The device supports a clock frequency of 35 MHz and functions reliably between -40°C and +85°C. Packaged in a compact 24-VQFN format, it integrates internal switches for efficient power management.

Feature Summary

Integrates a boost converter topology for driving high-voltage LED loads from low supply voltages
Provides sixteen individually controllable constant current channels with ON/OFF control capability
Includes built-in LED open detection (LOD) circuitry for fault monitoring and system reliability

Applications

LED backlighting systems requiring constant current regulation
General-purpose LED illumination circuits
Portable electronic devices utilizing surface-mount packaging

Procurement Notes

Verify the specific suffix 'RGER' against the manufacturer's official datasheet to confirm package type and reel specifications. Ensure compatibility with RoHS3 standards and check moisture sensitivity levels before assembly. Confirm that the 24-VQFN footprint matches your PCB design requirements.

Selection Notes

Select this component when designing circuits requiring multiple constant current outputs driven by a single controller. The boost topology allows operation from lower input voltages while maintaining higher LED forward voltages. Consider the 35 mA output limit and thermal dissipation capabilities of the VQFN package for your specific load requirements.

Part Context

This part belongs to the TLC5928 series of LED drivers manufactured by Texas Instruments. It is designed for applications needing multiple channels of regulated current. The RGER suffix indicates a specific tape-and-reel packaging configuration suitable for automated surface-mount assembly processes.
