LM3405A no load

Other Parts Discussed in Thread: LM3405A, LM3405

Hi,

Arrow states that the LM3405A features LOD (LED open detection) but I could not find anything about this protection in the datasheet.

What happens to the output if the LED is open/broken?

    I am also interested to know if the LM3405 features open circuit protection. I am using the LM3405 to drive multiple sets of LEDs at different times. I select what LED to drive by opening/closing some FETs acting as switches. There will be small periods of time where the LM3405 output will be open circuit. I need to know what will happen....preferably not via trial and error!
