TLC5960DAR

Overview

The TLC5960DAR is an eight-channel PWM LED driver controller manufactured by Texas Instruments in a 38-pin TSSOP package. It operates with a supply voltage range of 10V to 28V and supports input voltages from 3V to 5.5V. The device features a 250kHz PWM dimming frequency and includes four intelligent headroom voltage monitor (iHVM) outputs. It functions within a temperature range of -40°C to 85°C, providing high-voltage LED driving capabilities with integrated thermal management.

Feature Summary

• Eight-channel high-voltage LED driver architecture
• Integrated intelligent headroom voltage monitoring
• Scalable pulse-width modulation dimming control

Applications

• LED display systems
• General illumination lighting
• Backlighting applications

Procurement Notes

Verify the component against official Texas Instruments documentation to confirm the specific package variant and electrical characteristics. Ensure compatibility with system voltage requirements and thermal constraints before integration. Cross-reference part numbers to distinguish between tape-and-reel and tube packaging options if applicable.

Selection Notes

Select this component for designs requiring independent control of multiple LED channels with precise dimming resolution. Consider the thermal performance and heat dissipation requirements associated with the TSSOP-38 package when designing the PCB layout. Evaluate the iHVM functionality for optimizing power efficiency in complex LED arrays.

Part Context

This part belongs to the TLC5960 family of LED drivers from Texas Instruments. It is designed to replace older discrete LED driving solutions by integrating multiple channels and control logic into a single IC. The 'DAR' suffix typically indicates a specific tape-and-reel packaging configuration for automated assembly.

Replacement Considerations

The TLC5960DA is a related variant within the same product family. Verify pinout compatibility and functional equivalence before substitution.
