4.4 Load Regulation
4.4.1 Load Regulation of Converter 1
The load regulation for the converter 1 on the TPS54294EVM is shown in Figure 3 with the voltage axis
set to 1.2V ± 1%. On the EVM, the load regulation of converter 1 is independent on the load of converter
2.

4.4.2 Load Regulation of Converter 2
The load regulation for the converter 2 on the TPS54294EVM is shown in Figure 4 with the voltage axis
set to 3.3V ± 3%. For 5V input voltage, the converter 2 shows on the EVM some dependency on the load
of converter 1.
