Electrical performances
Table 1 shows the output loads for different input voltages. The maximum difference on the
output voltage is only about 50 mV.
Figure 16, Figure 17 and Figure 18 show the converter's efficiency depending on the output
load with various input voltage values.
Figure 16.
Efficiency versus output power at VIN = 125 VDC
