Overview
The TLC5926IDBQR is a Texas Instruments LED lighting driver IC featuring 16 constant-current sink channels. It utilizes a boost topology to drive LEDs with an output current of 120 mA and a maximum output voltage of 17 V. The device operates on a supply voltage between 3 V and 5.5 V, with a switching frequency of 30 MHz. It is housed in a QSOP-24 package and supports an operating temperature range from -40 °C to +125 °C.
Feature Summary
- Provides 16 independent constant-current sink outputs for uniform LED brightness control
- Integrates a boost converter topology to enable high-voltage LED string driving from low supply voltages
- Includes thermal shutdown protection to safeguard the device during overtemperature conditions
Applications
- LED backlighting systems for displays
- General LED illumination circuits
- Portable electronic devices requiring efficient LED drivers
Procurement Notes
Verify the specific suffix 'DBQR' corresponds to the QSOP-24 package and tape-and-reel packaging configuration. Confirm that the component meets RoHS compliance requirements for your target market. Ensure the ordering information matches the exact part number to avoid pinout or electrical specification mismatches.
Selection Notes
Select this component when a high channel count with integrated boost capability is required. It is suitable for applications needing precise constant-current regulation across multiple LEDs. Consider the thermal performance and package size constraints relative to the 120 mA per channel output requirement.
Part Context
This part belongs to the TLC5926 series of LED drivers from Texas Instruments. It is designed for applications requiring multiple constant-current sinks with integrated power conversion. The series offers solutions for driving LED arrays efficiently without external inductors in some configurations, though this specific model uses a boost topology.
Replacement Considerations
Check for direct pin-to-pin replacements within the same family, such as other variants of the TLC5926 series. Verify compatibility regarding package dimensions and electrical characteristics before substituting.
