TLC69661YBHR

Overview

The TLC69661YBHR is a Mini-LED local dimming backlight driver manufactured by Texas Instruments. It features 16 constant current sink channels with an output current of 60 mA and a maximum output voltage of 50 V. The device operates on a supply voltage between 3 V and 5.5 V. It supports PWM and hybrid dimming topologies within an operating temperature range of -40°C to +85°C. The component is housed in a DSBGA-24 package.

Feature Summary

• Supports local dimming for Mini-LED backlight applications
• Integrates LED open and short detection capabilities
• Enables hybrid dimming and phase shift functionality

Applications

• Mini-LED local dimming backlight drivers
• High-resolution display systems requiring precise zone control
• Consumer electronics with advanced lighting management

Procurement Notes

Verify the specific ordering suffix YBH to confirm the DSBGA-24 package configuration. Ensure compatibility with the required 3 V to 5.5 V supply rails and 60 mA channel current specifications. Confirm that the serial interface requirements align with the system design before procurement.

Selection Notes

Select this component when designing Mini-LED backlights requiring 16 independent zones. It is suitable for applications needing integrated fault detection and hybrid dimming. Verify that the DSBGA-24 package fits the PCB layout constraints and thermal requirements.

Part Context

This part belongs to the TLC69661 series of LED lighting drivers. It is designed specifically for local dimming applications, distinguishing it from general-purpose LED drivers by its integration of fault detection and specialized dimming controls for high-density LED arrays.

Replacement Considerations

The TLC69668YBHR is a confirmed substitute offering similar 16-channel architecture but with a higher 50 V output voltage capability compared to the standard 20 V variant. Verify pinout and software compatibility when substituting.
