Test Setup and Results
Figure 2. TPS54233EVM-373 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.
drain-to-source resistance of the internal MOSFET.
The load regulation for the TPS54233EVM-373 is shown in
