That 48-channel count means a single IC drives a full column of an LED matrix or a large alphanumeric display segment without external shift registers — the internal topology handles serial data in and latches it across all outputs simultaneously. The dual current setting (24.4 mA and 34.9 mA) lets the same BOM serve two brightness tiers — lower current for indoor signage where power budget matters, higher for outdoor or high-ambient-light panels where luminance must punch through. ## Package and thermal — 56-QFN exposed pad Housed in a 56-VFQFN exposed pad package (8x8 mm), the TLC5954RTQT requires a thermal via array under the centre pad to pull heat into the PCB ground plane.","metaTitle":"TLC5954RTQT LED Driver, 48-Channel, 24.4/34.9 mA, 56-QFN","metaDescription":"Texas Instruments TLC5954RTQT linear LED driver, 48 outputs, shift register topology, 10 V output, 24.4/34.9 mA per channel, 56-QFN.
