I'm currently running some power dissipation analysis or thermal calculation on a system and the way I do it is by looking at each part's data sheet and see if they list its power dissipation. Now some part's data sheet list power consumption and some other show the power dissipation.
My questions are:
How can I estimate the power dissipation if the only power listed is the power consumption? I think that power consumption is different from power dissipation, isn't that right?
Is the power consumption the power at the input of the electrical part? For example: how would I calculate the power consumption of a 30 watts power supply (120VAC input and 24V/1.25A output)?
