Depending on the equipment supplied, it’s possible to have several criteria to measure the
standby or light load performance of a converter. One criterion is the measurement of the
output power when the input power is equal to one watt. In
Table 10 the output power
needed to have 1 W of input power in a different line conditions is given.
Figure 24 and 25
show the diagram of the output powers corresponding to PIN = 1 W for different values of the
input voltage.
Another requirement (EuP lot 6) is that the input power should be less than 500 mW when
the converter is loaded with 250 mW. The performances are shown in
Figure 26 for external
biasing and in
Figure 27 for self biasing. In the former case the converter can satisfy even
this requirement.
