Power Dissipation
The low junction-to-case thermal resistance of the PWP package, along with
a good board layout, allows the TPS54x72EVM–222 EVMs to output full rated
load current while maintaining safe junction temperatures. With a 3.3-V input
source and a 6-A load, the junction temperture 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. The input voltage for the TPS54972 is 3.3 V and for
the TPS54672 and TPS54872, 5.0 V. Note that for a given output current the
TPS54972 dissipates less power due to the lower drain-to-source on
resistance of the MOSFETs. For additional information on the dissipation
ratings of the devices, see the individual product data sheets.
