Overview
The TLC5920DLG4 is a 16-channel LED driver manufactured by Texas Instruments, housed in a 48-pin SSOP package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -20°C to +85°C. The device features constant current outputs with a maximum output current of 30 mA per channel and a low-level sink capability of 640 mA. It functions as a linear shift register dimming controller with adjustable output voltage and works at a frequency of 10 MHz.
Feature Summary
- Provides 16 independent constant current outputs for precise LED control
- Integrates linear shift register functionality for sequential data input and dimming
- Supports both boost and buck topologies for flexible power management
Applications
- LED lighting driver systems
- LED display controllers
- General-purpose LED indicator arrays
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure compatibility with required packaging options such as tube or reel configurations. Confirm that the component meets RoHS compliance standards as specified in the latest datasheet. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring 16-channel constant current regulation for LED applications. Ensure the design accommodates the 48-SSOP package dimensions and thermal requirements. Verify that the system voltage aligns with the 4.5 V to 5.5 V operational range and that the interface logic matches the linear shift register input specifications.
Part Context
This part belongs to the TLC5920 series of LED drivers produced by Texas Instruments. It serves as a specialized integrated circuit for managing multiple LED channels efficiently. The DLG4 designation indicates a specific package variant within the broader product family, maintaining core electrical characteristics while differing in physical housing and potentially packaging format.
Replacement Considerations
Consult official substitution lists for direct replacements. Generic equivalents may not match the specific 16-channel constant current architecture or the 48-SSOP pinout configuration.
