Overview
The TLC69618RTWR is a Texas Instruments LED lighting driver IC designed for 128 mini-LED matrix local dimming backlight applications. It features a 16-channel architecture with an integrated current sink capable of delivering 60 mA per channel. The device operates within a supply voltage range of 3 V to 5.5 V and supports a maximum output voltage of 20 V. It utilizes a high-speed serial interface for data transmission and functions at a clock frequency of up to 20 MHz. The component is housed in a WQFN-24 package, suitable for surface mount installation, and is rated for operation between -40°C and +85°C.
Feature Summary
- Supports flexible local dimming control for mini-LED matrix backlights
- Integrates hybrid dimming and phase shift capabilities
- Includes built-in LED open and short detection mechanisms
Applications
- Mini-LED matrix local dimming backlight systems
- High-resolution display backlight drivers
- Automotive or industrial display modules requiring precise channel control
Procurement Notes
Verify the specific ordering suffix RTW corresponds to the required tape and reel packaging configuration. Confirm that the WQFN-24 package dimensions align with the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the datasheet revision to confirm feature compatibility.
Selection Notes
Select this component when a 16-channel driver with 60 mA output capability is required for mini-LED applications. Consider the WQFN-24 package size constraints and the need for local dimming functionality. Evaluate the serial interface speed against system timing requirements. Verify thermal performance within the specified ambient temperature range.
Part Context
This part belongs to the TLC69618 series of LED drivers from Texas Instruments. It is specifically engineered for time-multiplexing and local dimming tasks in advanced display technologies. The RTWR variant denotes the specific reel-based packaging format used for automated surface mount assembly processes.
Replacement Considerations
Consult official substitution lists for compatible parts within the same family. Verify pinout and electrical parameter equivalence before swapping components.
