DM631 16 channel LED driver
As I understand it the outputs on the DM631 (which are kind of inputs as they sink current) will be happy as long as the 17V maximum voltage and maximum current rating is not exceeded?


Almost. If you set the DM631 to supply 20 mA (3kΩ between REXT and GND), a LED strip that needs 80 mA will not work as expected. The DM631 may be happy but you and your LEDs may not be.
