Test Setup and Results
shows the efficiency for the TPS5432EVM-116 at lower output currents between 0.001 A and 3 A
at an ambient temperature of 25°C.
Figure 2. TPS5432EVM-116 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.
