Posted on December 30, 2017 at 11:16I have a LED2001PHR based LED driver that is designed to drive a string of LEDs at 5.2V and 3A. When I apply power and the LEDs are connected, the LEDs flash for a fraction of a second and then go off telling me t...

Posted on March 08, 2016 at 05:48Hi, I'm trying to build a constant current LED driver using the ST1CC40. I built a prototype version and noticed that with no load attached, the entire Vin (in my case its 12V) is seen at the output. Is this normal? ...
