Test Setup and Results
shows the efficiency for the TPS54319EVM-626 at lower output currents between 0.001 A and 3
A at an ambient temperature of 25°C.
Figure 2. TPS54319EVM-626 Low Current Efficiency
The efficiency may be lower at higher ambient temperatures, due to temperature variation in the
drain-to-source resistance of the internal MOSFET.
