By using the thermal metrics found in the converter data sheet and a few simple equations, the thermal performance of a given application can usually be estimated well enough for engineering purposes. The considerations given here can provide sufficient information about the thermal performance for comparison purposes or may even provide a good estimate for a final design. Of course, as with any engineering endeavor, testing of a prototype application will provide the best possible measure of performance in the final product; however using the guidance in this paper, your first design is more likely to be your final design.
