Power Dissipation
The low junction-to-case thermal resistance of the PWP package, along with
a good board layout, allows the TPS54380EVM-001 EVMs to output full rated
load current while maintaining safe junction temperatures. With a 3.3-V input
source and a 3-A load, the junction temperature is approximately 60
°
C, while
the case temperature is approximately 55
°
C. The total circuit losses at 25
°
C
are shown in Figure 2–3. Power dissipation is shown for input voltages of 3.3 V
and 5.0 V.
For additional information on the dissipation ratings of the devices, see the
individual product data sheets.
