Burst mode and output voltage ripple
Figure 22. ENERGY STAR^® efficiency criteria
The power supply presented is from a standard model and, in order to be compliant with the
ENERGY STAR^® requirements, needs to have efficiency higher than 71.6%. If the self-
supply is excluded, the efficiency results (seeTable 9) are higher than the recommended
value within the whole input voltage range.

Light-load performance
The input power of the converter has been measured in no-load condition for different input
voltages and the results are given in Table 12.
