Figure 15. No-load consumption
Some measurements with low output loads were also taken. They refer only to the operation
of the auxiliary stage, while the other stages are off. Results are shown in
Table 7
13221 - “1-Watt Standby” to be met. To be more precise, when the output power is reduced
to 0.5 W, the input power is lower than 1 W (efficiency greater than 50 %). This is a very
common requirement for power supply manufacturers.
