Using surface mount power MOSFETs in processor power supplies

The price of surface mount power MOSFETs has steadily dropped over the years, to the point where now they are essentially the same price as TO-220s (for the same die). When account is taken of heat sinking costs of the TO-220 packagethe heat sink itself, possibly a screw, laborthe surface mount part may actually turn out to be cheaper.

For this reason, surface mount power MOSFETs are becoming increasingly popular for use in processors' switch-mode power supplies. Ensuring that they operate as planned requires careful attention to their thermal environment, in particular pad size. This application note gives the designer and the layout specialist the information necessary to create a successful design.
