4.2 Efficiency
The efficiency of this EVM peaks at a load current of about 300 mA at 5-V input and 800 mA at 12-V input,
then decreases as the load current increases toward full load.
Figure 1 shows the efficiency for the EVM
at an ambient temperature of 25°C.
Figure 1. TPS55340EVM-017 Efficiency
The efficiency may be lower at higher ambient temperatures, due to temperature variation in the drain-to-
source resistance of the internal MOSFET.
4.3 Output Voltage Load Regulation
Figure 2 shows the load regulation for the EVM.
