TLC5929DBQ

Overview

The TLC5929DBQ is a Texas Instruments LED lighting driver IC featuring 16 constant current outputs in a 24-pin QSOP package. It operates on a 3V to 5.5V supply with a maximum output voltage of 10V and per-channel current of 50mA. The device utilizes a boost topology and supports a clock frequency up to 33MHz. It functions within an ambient temperature range of -40°C to +85°C.

Feature Summary

Provides 16 individually addressable constant current channels for uniform LED brightness control
Integrates open-load detection capabilities to identify LED failures or disconnections
Supports digital on/off control for individual channel management via serial interface

Applications

LED backlighting systems
General LED illumination circuits
Portable electronic display drivers

Procurement Notes

Verify the specific suffix 'DBQ' confirms the 24-pin QSOP package variant. Confirm RoHS compliance status matches project requirements. Ensure the operating environment stays within the specified -40°C to +85°C thermal limits. Validate that the 50mA per-channel current rating meets the target LED load specifications without exceeding absolute maximum ratings.

Selection Notes

Select this component when 16 independent constant current outputs are required in a compact surface-mount package. It is suitable for designs needing integrated fault detection and simple serial control. Consider the 3V to 5.5V input range compatibility with standard logic levels. Evaluate the 50mA output capability against the specific forward current requirements of the connected LEDs.

Part Context

This part belongs to the TLC5929 series of LED drivers from Texas Instruments. It shares functional similarities with other members like the TLC5928, though output current and internal topology may differ. The DBQ suffix specifically denotes the plastic small-outline package type used for space-constrained PCB layouts.
