Overview
The TLC5929RGER is a Texas Instruments LED lighting driver IC featuring 16 constant current outputs in a 24-VQFN package. It operates on a boost topology with an output voltage of 10 V and supports up to 50 mA per channel. The device accepts input voltages between 3 V and 5.5 V, drawing a maximum supply current of 14 mA. It functions at clock frequencies up to 33 MHz and withstands operating temperatures from -40°C to +85°C.
Feature Summary
- Provides 16-channel constant current regulation for uniform LED brightness control
- Integrates internal boost converter topology to drive high-voltage LED strings
- Includes hardware-based LED open detection for fault monitoring
- Supports digital ON/OFF control via serial interface
Applications
- Signage backlighting systems
- General LED illumination arrays
- Industrial indicator panels
Procurement Notes
Verify the specific suffix RGER corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 24-VQFN footprint matches the target PCB layout dimensions. Ensure compliance with RoHS3 standards and check moisture sensitivity level requirements for storage and reflow conditions before procurement.
Selection Notes
Select this component when designing circuits requiring precise current regulation for multiple LEDs without external sense resistors. The integrated boost capability simplifies power management compared to linear drivers. Consider the thermal performance of the exposed pad VQFN package for heat dissipation in dense layouts.
Part Context
This part belongs to the TLC5929 series of LED drivers designed for applications needing high channel counts in compact form factors. It complements other variants like the TLC5929DBQ which offers different packaging options while maintaining identical electrical characteristics and functionality for flexible design integration.
Replacement Considerations
TLC5929RGET serves as a verified alternative within the same family, offering identical electrical specifications but potentially differing in reel quantity or specific manufacturing lot configurations.
