TLC59291RGET

Overview

The TLC59291RGET is a Texas Instruments LED lighting driver IC featuring 16 constant-current outputs with a boost topology. It operates on a 3V to 5.5V supply, delivering up to 50mA per channel at a maximum output voltage of 10V. The device utilizes a serial interface with a clock frequency of 33MHz and is housed in a 24-VQFN (4x4) package. It supports dimming functions and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates 16 linear constant-current channels for precise LED control
• Incorporates an internal boost converter topology for flexible drive configurations
• Supports digital dimming capabilities via a high-speed serial interface

Applications

• LED backlighting systems
• General LED illumination modules
• Portable electronic display drivers

Procurement Notes

Verify the specific suffix 'RGET' corresponds to the 24-VQFN package and reel packaging configuration. Confirm that the 33MHz operating frequency requirement aligns with the system's serial clock constraints. Ensure thermal management strategies accommodate the 24-VQFN form factor during operation.

Selection Notes

Select this component when a 16-channel solution with integrated boost capability is required. The 33MHz speed offers faster data transfer compared to standard 20MHz variants. Consider the 24-VQFN footprint for space-constrained designs requiring surface-mount assembly.

Part Context

This part belongs to the TLC59291 series, designed specifically for LED lighting applications. It distinguishes itself from similar models like the TLC5929 by offering a higher 33MHz clock rate. The RGET designation indicates the specific tape-and-reel packaging format suitable for automated surface-mount production lines.

Replacement Considerations

The TLC5929RGET serves as a functional substitute with identical pinout but operates at a lower 20MHz frequency. Verify if the system timing budget accommodates the reduced clock speed before swapping components.
