Efficiency
The efficiency of this EVM peaks at a load current between 3 A and 6 A and then decreases as the load
current increases toward full load.
current increases toward full load.
shows the efficiency for the EVM at an ambient temperature of
25°C.
Figure 1. EVM Efficiency at 25°C
The efficiency is lower at higher ambient temperatures, due to temperature variation in the drain-to-source
resistance R
resistance R
DS_ON
of the internal MOSFETs.
