Test Setup and Results
4.2
Efficiency
The efficiency of this EVM peaks at a load current of about 400 mA at 2.9-V input and 700 mA at 4.2-V
input, then decreases as the load current increases toward full load.

EVM at an ambient temperature of 25°C.
Figure 1. TPS55330EVM-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.
