TLC69608YBHR

Overview

The TLC69608YBHR is an LED lighting driver IC designed for 128 mini-LED matrix local dimming backlight applications. It features 16 channels with integrated current sinks, supporting PWM dimming at up to 30mA per channel. The device operates on a supply voltage range of 3V to 5.5V and supports a maximum output voltage of 20V. It utilizes a 24-pin DSBGA package (1.58x2.43mm) and functions within a temperature range of -40°C to +85°C. The component integrates time-multiplexing capabilities for efficient matrix driving.

Feature Summary

• Integrates 16-channel constant current sinks for precise LED control
• Supports high-resolution PWM dimming for localized brightness adjustment
• Utilizes time-multiplexing architecture to drive complex mini-LED matrices efficiently

Applications

• Mini-LED display backlight systems requiring local dimming
• High-end LCD panels needing enhanced contrast ratios
• Portable electronic devices demanding thin form factor backlight drivers

Procurement Notes

Verify the specific suffix YBHR corresponds to the required 24-pin DSBGA package configuration. Confirm that the operating temperature range of -40°C to +85°C meets the target application's environmental requirements. Ensure compatibility with the host controller's interface protocols for data transmission and synchronization signals before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring independent control over multiple LED zones in a compact footprint. The integrated current sinks reduce external component count compared to discrete solutions. Consider the 20V output limit and 30mA per channel capability when sizing the LED array. Verify power dissipation constraints within the small DSBGA package for thermal management strategies.

Part Context

This part belongs to the Texas Instruments TLC6960x series of LED drivers. The series includes variants like TLC69602, TLC69604, and TLC69608, differing primarily in channel counts and multiplexing configurations. These devices are engineered specifically for advanced backlighting applications where local dimming improves image quality and energy efficiency in modern display technologies.

Replacement Considerations

Direct substitutes include other members of the TLC6960x family such as TLC69602 or TLC69604 if channel count adjustments are acceptable. Cross-reference pinout compatibility and electrical specifications carefully. No alternative part numbers are explicitly confirmed as direct replacements in public documentation without functional verification.
