Ohai thar. I want to run a PMZ390UN at 3 amps 1 volt which is 3 watts. I really don't know too much about cooling SMD parts, it says the thermal characteristics are 50k/Wwand then below that it says 670k/w.
It seems that the 50k/w parameter is for "junction to solder" but how does that differ from a normal connection to the PCB?
I guess in short what I want to ask is, can this be done safely with air cooling and maybe some extra copper on the pin layout?
