LTC3490: Possible to use 2 or more in parallel?

In theory, current sources including LED drivers can be paralleled easily so I would not expect a problem.  There is no trick - just take two identical LTC3490 circuits and connect the LED pins together.  The LTC3490 works most simply if the input voltage is less than the LED voltage, so that would be the preferred way to operate two LTC3490s in parallel.
