Energy saving performances

The VIPer31 allows the design of applications compliant with the most stringent energy saving regulations. In

order to show the typical performances achievable, the active mode average efficiency and the efficiency at

10% of the rated output power of a single output flyback converter using VIPer31 have been measured and are

reported in Table 9. In addition, Figures 52 and 53 show no-load and light load consumptions.
