Package
temperature rise numbers are all approximate, and
there are many factors that will affect these
numbers.
size, shape, thickness, position, location, and even
board temperature. Other factors are, trace width,
total printed circuit copper area, copper thickness,
single or double-sided, multilayer board and the
amount of solder on the board. The effectiveness of
the PC board to dissipate heat also depends on the
size, quantity and spacing of other components on
the board, as well as whether the surrounding air is
still or moving.

Furthermore, some of these components such as
the catch diode will add heat to the PC board and
the heat can vary as the input voltage changes.
For the inductor, depending on the physical size,
type of core material and the DC resistance, it could
either act as a heat sink taking heat away from the
board, or it could add heat to the board.
