Each channel sinks up to 60 mA, and the output voltage compliance goes to 17 V, giving you headroom for series LED strings or higher-voltage rails. The shift register interface means you clock in grayscale data and latch it — no PWM from the MCU needed per channel. ## Package and board integration — 24-VFQFN with exposed pad The 60 mA per channel times 12 channels is 720 mA total sink current — without that pad soldered to a ground plane, the junction creeps above the 85°C ambient rating. Surface-mount only — no through-hole variant. The 24-VQFN (4x4) supplier package is the same footprint as other TI VQFN LED drivers, so a board layout for the TLC5940 family will often accept this part with a firmware change.","metaTitle":"TI TLC5971RGET LED Driver, 12-Ch 60mA, 24-VFQFN","metaDescription":"Texas Instruments TLC5971RGET linear LED driver: 12 channels, 60 mA per channel, shift register topology, 24-VFQFN package.
