First off , thank you for that design rule check !! really helped out a lot. Second off , please forgive any current and future ignorance. First time posting here, first time even asking for help on this stuff
now to the first board, a little more explanation :
initially based off of this design, its an attempt to make the whole thing smaller and also to put in an optional volt divider for the mosfet due to the vgs being way too high for the mosfets we were using :
it is powering a 100w rgb led , each channel is one of those small mosfet circuits , so they are handling between a 26v and 36v input at around 900ma.
the mosfet we are currently using is : http://www.newark.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10001&langId=-1&urlRequestType=Base&partNumber=53Y4834&storeId=10194
much beefier mosfet which i prefer not to use but is another option as long as i put in bigger spacing :
I will try to draw up some more details to more properly explain the whole scheme. for now maybe the current answer can address the first circuit board design?
