7.3.7 Output Current Rating
The maximum output current that the TPSM84209 can deliver is a function of input voltage, output voltage, and ambient temperature. The TPSM84209 is capable of delivering up to 2.5 A of output current; however refer to Figure 21 and Figure 22 for maximum current ratings based on operating conditions of the specific application.
