Application Hints
(Continued)
As shown in the graph below, increasing the copper area
beyond 1 square inch produces very little improvement. The
minimum value for θ
for the TO-263 package mounted to a
JA
PCB is 32˚C/W.
Figure 2 shows the maximum allowable power dissipation
for TO-263 packages for different ambient temperatures,
assuming θ
is 35˚C/W and the maximum junction tempera-
JA
ture is 125˚C.
