31 / 37 page  DS11873 Rev 5 31/37 VIPer11 Application information 37 6.2 Energy saving performance The device allows designing applications to be compliant with the most stringent energy saving regulations. In order to show the typical performance is achievable, the active mode average efficiency and the efficiency at 10% of the rated output power of a 5 V/1.6 A non- isolated flyback and 5 V/360 mA buck converters adopting VIPer11, have been measured and are reported in Table 9. In addition, no-load and light load consumptions are shown from Figure 41 to Figure 44. Table 9. Power supply efficiency, VOUT = 5 V Parameter VIN 10 % output load efficiency [%] Active mode average efficiency [%] Pin at no-load [mW] Flyback non iso. 5 V/1.6 A 115 VAC 78.3 78.5 3.9 230 VAC 71.4 79.4 8.2 Buck 5 V/360 mA(1) 115 VAC 73.9 71.6 12.1 230 VAC 69.1 69.8 16.2 1. 5 mW bleeder connected at the output.
