I’ve had a number of requests to put up a constant voltage version of my COB LED Driver Selection Tool so I drafted one up today. Please see the notes at the bottom of this post for some important additional info. Also, if you’d like to see any COBs added, let me know which ones and I’ll see if I can include them.
Constant voltage drivers are becoming more popular lately. They’re safer, flexible, and often cheaper than their constant current counterparts, but it can be a little more difficult to pick the right CV driver for your system than it would be for a CC build. Don’t sweat though, it’s really not very hard. All you need is an understanding of how parallel wiring works and to know how to manipulate forward voltage and current numbers using data sheets or product simulators.
Below are the steps to take to find a suitable constant voltage driver. Continue reading
