For my LED project I got two 150W dc dc controllers. I used a 12v supply and use the two controllers to drive two channels of LEDs at different voltages, 18v and 16v. However, both these controllers seem to not work when I start them untill I fiddle on the two onboard mosfets with a screw driver. Even that is a hit or miss as ive to repeat the same thing several times before they start working. Once up, they dont stop untill i pull the power.What can be the problem? Is it faulty boards? Or is there a problem with my application? Is there a better solution?I need to drive the two LED channels variably from 15 to 18vdc. via /r/DIY http://ift.tt/2jGMmVu
