4.4 Load Regulation
4.4.1 Load Regulation of Converter 1
The load regulation for the converter 1 on the TPS542951EVM is shown in Figure 5. On the EVM, the
load regulation of converter 1 is independent on the load of converter 2.
Figure 5. TPS542951EVM Converter 1 Load Regulation
4.4.2 Load Regulation of Converter 2
The load regulation for the converter 2 on the TPS542951EVM is shown in Figure 6. For 5V input voltage,
the converter 2 shows on the EVM some dependency on the load of converter 1.
