I'm looking for a DM13A 16-bit Constant Current LED Driver

Does exist in some where?
Thank You.

Doesn’t look like anyone has made one yet. Depending on what you want to do a 24 pin generic IC would do the trick if you are interested in the DIP pcb footprint. If you want one of the SMD footprints you would probably need a custom part or at least an svg of the desired footprint. To use a generic IC, drag one from core parts in to the sketch and then in Inspector (the lower right window) change the number of pins to 24 (width should default to .3in if not, set that too.) You can then click on the labels and edit the text to match the datasheet labels. There may be appropriate SMD footprints selectable in Inspector as well (although checking the output footprint before ordering boards would be wise.)
