Does anyone know a simple formula to estimate heat dissapation in a switching mosfet? Looking online it gets kinda confusing for me and im not the greatest at math or all the formula stuff, maybe there's a simpler formula out there just for estimates sake?the variables I know and I guess are important are rds(on), input capacitance, the drain/source current, the gate resistor/driver output impedanceI know the heat dissapation without switching, but I wanna see the different heat dissapation at different switching frequency's/different driver capabilities so I can see if I can get away without a mosfet driver at the frequency I want to switch at, and/or the frequency cutoff where I can just use a resistor
So .17*13v*6a*10.4us= 137.904 ? uC?
137.904*15000*2= 4137120?? What does this mean, it seems quite large, even if I cut down the switchin time dramatically this seems way too high unless its really a small unit
I think perhaps this can do what I want? http://www.irf.com/product-
problem isn't while looking straight at it, but if you move your eyes quickly it tracks across your vision,
