Overview
The TLC69661RTWR is a Texas Instruments LED lighting driver IC designed for mini-LED matrix local dimming backlight applications. It features 16 channels with independent PWM control and supports up to 16-bit resolution per channel. The device operates on an input voltage range of 3 V to 5.5 V, delivering a maximum output current of 60 mA per channel. It utilizes an SPI interface for data transmission and functions within a temperature range of -40°C to +85°C. The component is housed in a WQFN-24 package.
Feature Summary
- Provides independent 16-bit PWM control for each of the 16 output channels to enable precise pixel-level brightness adjustment.
- Integrates local dimming capabilities specifically optimized for mini-LED matrix backlight architectures.
- Supports serial communication via SPI interface for efficient data loading and configuration.
Applications
- Mini-LED matrix local dimming backlight systems
- High-resolution display panels requiring precise LED control
- Advanced LCD backlight units
Procurement Notes
Verify the specific suffix RTWR corresponds to the required tape and reel packaging format. Confirm that the WQFN-24 package dimensions align with your PCB footprint requirements. Ensure the 60 mA output current specification meets the drive requirements of your target LED array. Validate compatibility with your system's SPI clock rates and voltage levels before finalizing procurement.
Selection Notes
Select this component when designing displays requiring high contrast through local dimming. It is suitable for applications needing 16-channel constant current drivers with high-resolution PWM. Consider the WQFN-24 package size for space-constrained designs. Compare against other TLC696xx series variants if different channel counts or current limits are needed.
Part Context
This part belongs to the TLC696x1 family of 16-channel local dimming backlight LED drivers from Texas Instruments. These devices are engineered to bridge the gap between standard LED drivers and complex display controllers by offering integrated PWM generation and local dimming logic.
Replacement Considerations
Check for direct substitutes within the TLC6966x series for similar channel counts. Verify pin-to-pin compatibility if replacing existing designs. Consult official TI documentation for any updated revisions or end-of-life notices regarding this specific marking code.
