Buck converter power dissipation calculator
WebWith a maximum duty factor of 94%, a 30A load current, and a 4.13mΩ maximum R DS (ON), these paralleled MOSFETs dissipate about 3.5W. Supplied with 2in² of copper to dissipate that power, the overall Θ JA should be about 18°C/W. Note that this thermal resistance value is taken from the MOSFET data sheet. WebTo better understand how thermal resistance is used, lets look at the following example: Power dissipated: 2W. RθJC = 4°C/W. RθCH = 0.25°C/W. RθHA = 6°C/W. TA = 25°C. Starting with the thermal equivalent of Ohm's Law: We want to solve for our junction temperature rise , so T becomes T J. Our power dissipated, P, is 2W.
