Hi,
I am planning to make a 4+1 car amplifier based on LM4780(4*60+120W). I enclosed the component layout of my desing. Two 4780s are BPA and the left ones stereo for fullrange. The copper drawing is not finished yet and I would like to ask someone here. The PCB will be mount on the heatsink from the SMPS mosfets and 4780s' case via bulk copper used as bus for industrial electrical(2"*0.5"*5"). My heatsink is 5"*6.5" and has 17 fins (3cm). Will this heatsink be enough for my amp?
All comments will be very useful on this stage! |
