TLC69604YBHR

Overview

The TLC69604YBHR is an LED lighting driver IC designed for mini-LED matrix local dimming backlight applications. It features a 64-channel output configuration with integrated current sinks, providing independent pixel-level control. The device supports 16-bit PWM dimming resolution to ensure high contrast and accurate color reproduction. Operating within a supply voltage range of 3 V to 5.5 V, it delivers a constant output current of 30 mA per channel. The component is housed in a compact 24-pin DSBGA package measuring 1.58 x 2.43 mm, suitable for space-constrained designs.

Feature Summary

• Provides independent 16-bit PWM control for each of the 64 channels to enable precise local dimming.
• Integrates linear constant current sinks capable of delivering up to 30 mA per output channel.
• Supports serial interface communication for efficient data transmission and control signal management.

Applications

• Mini-LED matrix local dimming backlight systems
• High-end display panels requiring pixel-level brightness control
• Advanced LCD backlight units

Procurement Notes

Verify the specific ordering suffix and package variant against the manufacturer's official documentation to ensure compatibility with the target design. Confirm that the selected component meets all required environmental specifications and regulatory standards for the intended application environment before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring high-resolution local dimming for mini-LED arrays.
