TLC5929PWPR

Overview

The TLC5929PWPR is a Texas Instruments LED lighting driver IC featuring 16 constant current outputs in an HTSSOP-24 package. It operates on a boost topology with an input voltage range of 3 V to 5.5 V, delivering up to 50 mA per channel and reaching a maximum output voltage of 10 V. The device supports a 33 MHz operating frequency and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Provides 16 independent constant current channels for uniform LED illumination
• Integrates internal boost converter to drive high-voltage LED loads from low supply voltages
• Includes hardware-based open detection circuitry for fault monitoring

Applications

• General LED lighting modules requiring uniform brightness
• Backlighting systems for displays and signage
• Portable electronic devices utilizing high-efficiency LED arrays

Procurement Notes

Verify the specific suffix 'PWPR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the HTSSOP-24 package dimensions align with the target PCB footprint. Ensure the selected component meets RoHS compliance standards for the intended market regulations.

Selection Notes

Select this component when designing circuits that require multiple constant current sources driven by a single boost regulator. The 50 mA output capability suits standard indicator LEDs or small array segments. Consider thermal management requirements given the integrated power stage within the compact package.

Part Context

This part belongs to the TLC5929 series of LED drivers designed for applications needing multiple regulated current outputs. It simplifies design by combining the driver logic and boost converter into a single solution, reducing external component count compared to discrete implementations.

Replacement Considerations

TLC5929PWP serves as the tube-packaged alternative offering identical electrical characteristics.
