16-channel constant-current sink with shift register interface
The TLC59283RGET is a linear LED driver from Texas Instruments, built around a shift register topology that clocks in grayscale data at up to 35 MHz. It sinks 45 mA per channel across 16 outputs, with the output voltage rated to 10 V.
Package and board-fit for the 24-VQFN
Housed in a 24-VFQFN exposed pad package (4x4 mm body, supplier device package 24-VQFN), the TLC59283RGET mounts on the PCB surface with the thermal pad soldered to a ground plane for heat sinking. The 0.5 mm pitch QFN demands careful solder paste stencil design to avoid bridging between the centre pad and the perimeter I/O pads.
