I am using LM3643 to drive one LED only. LED connects to LED1. The current is set to 725mA. It is used in strobe mode. The strobe signal is pulse of 30Hz, duty cycle 50%. The application drive this LED in 30Hz with 50% mode for at most 10 minutes and rest for another at least 10 minutes. Under this application situation, what is the normal working life of LM3643? If it degrades, what is the degradation sign?
Thank you very much.
