Figure 3 shows a board layout using the SOP-8-P
package. The demoboard is made of FR-4 material
and is a two-layer PCB. The board size and thickness
are 65mm* 65mm and 1.6mm. The copper thickness
of top and bottom layers is 2 oz. The partial layout
around APL5332 is as the details above and shown in
the figure 2. It uses 15mil vias to connect the top and
bottom ground plane. The
θ
JA
of the APL5332 (SOP-8-
P) mounted on the demodoard is about 41.3
o
C/W in
free air. Assuming the T
A
=25
o
C and the maximum
T
J
=150
o
C (typical thermal limit temperature), the maxi-
mum power dissipation is calculated as :
P
D(max)
= (150 - 25) / 41.3
= 3.03W
If the T
J
is designed to be below 125
o
C, the calculated
power dissipation should be less than :
P
D
= (125 - 25) / 41.3
= 2.42W
