Product Overview
The Texas Instruments TLC5925 is a 16-channel constant-current LED sink driver for LED applications. Its OUT0 to OUT15 outputs provide constant-current sink channels, with output current adjustable from 3 mA to 45 mA using an external R-EXT resistor. Recommended operation covers a 3 V to 5.5 V supply range and output voltage up to 17 V.
The device is available in 24-pin SSOP DBQ 8.65 mm x 3.90 mm, 24-pin SOIC DW 15.40 mm x 7.50 mm, and 24-pin TSSOP PW 7.80 mm x 4.40 mm package options. Thermal data is specified for JEDEC 1-layer and 4-layer boards with no airflow, supporting package-level thermal review during assembly planning.
Interface timing includes 30 MHz maximum clock frequency for cascade operation, 15 ns minimum LE and CLK pulse durations, 300 ns minimum OE pulse duration, and SDI setup and hold requirements of 3 ns and 2 ns. Applications should remain within the stated electrical, thermal, and absolute maximum ratings.

Procurement Notes
When requesting a quote for TLC5925, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For LED and optoelectronic sourcing, brightness bin, wavelength or color temperature bin, forward voltage range, viewing angle, moisture sensitivity level and soldering process limits may affect final selection, availability and lead time.
