28 / 39 page  5.2 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, Figure 44, Figure 45 show no-load and light load consumptions. Table 9. Power supply efficiency, VOUT = 15 V Parameter VIN 10% output load efficiency [%] Active mode average efficiency [%] Pin @ no-load [mW] Flyback iso, 15V/1.2A 115 VAC 83.2 85.9 26.0 230 VAC 77.4 86.6 29.7 Figure 44.
