TLC5928DBQ

Overview

The TLC5928DBQ is a Texas Instruments linear LED driver IC featuring 16 constant-current outputs in a 24-SSOP package. It operates on a 3V to 5.5V supply with a maximum output voltage of 17V and per-channel current of 35mA. The device utilizes a serial shift register interface with a data transfer rate of 35MHz. It supports PWM dimming and includes internal switches for direct LED connection. The component functions within an ambient temperature range of -40°C to 85°C.

Feature Summary

Integrates 16 independent constant-current channels for uniform LED brightness control
Utilizes a serial shift register topology for simplified digital interface connectivity
Supports pulse-width modulation (PWM) dimming for precise intensity adjustment
Features internal power switches eliminating the need for external components

Applications

LED lighting driver systems
General-purpose LED display panels
Industrial indicator arrays

Procurement Notes

Verify the specific suffix 'DBQ' corresponds to the tube packaging variant rather than the reel-based 'DBQR'. Confirm RoHS3 compliance status and ensure the 24-SSOP footprint matches the target PCB design. Cross-reference the manufacturer part number against authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Selection Notes

Select this component when 16 synchronized constant-current channels are required without open-circuit detection features. Choose the DBQ suffix specifically for tube-based manufacturing processes instead of tape-and-reel automation. Ensure the application requires linear regulation topology and can accommodate the specified 35mA per-channel limit within thermal constraints.

Part Context

This part belongs to the TLC5928 family of 16-channel LED drivers from Texas Instruments. It serves as a core component in power management solutions for illumination applications. The device complements other variants like the TLC59281 and TLC59282, which offer different current ratings or additional diagnostic capabilities such as LED open detection.
