Power Dissipation
The low junction-to-case thermal resistance of the PWP package with
PowerPad
, along with a good board layout, allows the TPS54x80EVM-228
to provide full rated load current while maintaining safe junction temperatures.
The total board losses at 25
°
C are shown in Figure 2-9. The input voltage is
5 V. The load current shown in the Figure 2-3 is the sum of currents of both
core and I/O regulators.
The temperature rise of PowerPad
, which is only few degrees below the
junction temperature, has been measured at 6 A (TPS54680/TPS54610) and
8 A (TPS54880/TPS54810) loads. At 6-A load current from each channel, the
temperature rise does not exceed 33
°
C and at 8 A the measured temperature
rise was 54.2
°
C. The overall dissipated power for these two conditions is 3.8
W and 7.2 W respectively. These test data are taken without airflow at room
temp 22
°
. For the additional information on the dissipation ratings of the
devices, see the individual product data sheets.
