Hi
I was looking at web bench for ic to convert 12V to 5V with 4Amp which I found TPS565208.
My question is power dissipation and how hot the ic will get
Base my understanding you calculate junction temp: (Vout-Vin)Iout x (1-%Efficiency) x Ramp= (12-5)*4* (1-.94)*95C/W = 159.6C
But if you look at the web bench you will see the IC junction temperature 80.4C so which one is correct
even if look at TPS565208 EVM does this board can handle 3Amp without heating up
