Will LED2000 destroy itself if the LED load is removed while operating?

We have been using the LED2000 and LED2001 for years with great success. We have a new design where it is possible that the LED loading the output can be disconnected during operation. The LED would be running around 1.5A. That would result in a switcher running with zero current feedback. Would it go to a high output voltage and blow itself up?

Hi, it's been 5 days since I posted this and nobody has replied. Am I posting to the wrong place? Am I doing something wrong with the way I posted it? I was assuming someone from ST would reply, or is this board not monitored by ST support? Any suggestions appreciated.

Hi Lloyd,

I don't have any experience with the LED2000, but I'm currently working o a design with the LED6000. I don't think the device will be blown when you life disconnect the load. It will go to higher voltage since it wants to drive the current, but it should stay at max Vcc. Of course, the output caps have to be able to handle that.
