Test Setup and Results
2.2
Efficiency
The efficiency of this EVM peaks at a load current of about 0.07A with V
IN
= 8V, and then decreases as
the load current increases towards full load.
shows the efficiency for the TPS54061EVM-142 at
an ambient temperature of 25°C.
Figure 1. TPS54061EVM-142 Efficiency
shows the efficiency for the TPS54061EVM-142 at lower output currents between 0.001A and
0.2A at an ambient temperature of 25°C.
Figure 2. TPS54061EVM-142 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.
