TLC69668RTWR

Overview

The TLC69668RTWR is a Texas Instruments LED lighting driver IC designed for 128 mini-LED matrix local dimming backlight applications. It features a single output with a maximum current of 60 mA and an output voltage of 50 V. The device operates on a power supply voltage ranging from 3 V to 5.5 V, with a maximum rating of 5.5 V. It supports a working frequency of 20 MHz and is housed in a WQFN-24 package. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

Supports 128 mini-LED matrix configurations for local dimming backlight control
Integrates 16-channel time-multiplexing capability for efficient matrix driving
Provides linear constant current PWM dimming functionality

Applications

Mini-LED matrix local dimming backlight systems
High-resolution display backlight drivers
Advanced LCD backlight control units

Procurement Notes

Verify the specific suffix RTWR corresponds to the required tape and reel packaging format when ordering. Confirm that the WQFN-24 package dimensions align with the target PCB footprint. Ensure the 60 mA output current specification meets the load requirements of the intended mini-LED array configuration without exceeding thermal limits.

Selection Notes

Select this component for designs requiring precise local dimming control in mini-LED matrices. The 60 mA sink current suits high-brightness LED strings. Consider the 20 MHz operating frequency for signal integrity. The wide input voltage range allows flexibility in system power design. Verify compatibility with existing controller interfaces supporting the required multiplexing scheme.

Part Context

This part belongs to the TLC69668 series of LED lighting driver ICs from Texas Instruments. It is specifically engineered for complex backlight architectures utilizing mini-LED technology. The series focuses on providing integrated solutions for local dimming, reducing external component count while maintaining high performance standards for modern display applications.

Replacement Considerations

The TLC69668RTWR serves as a direct replacement for earlier versions or variants within the same functional family where 60 mA output and 128 matrix support are required. Cross-reference with other TI LED drivers only if pinout and electrical parameters match exactly.
