Functional checking
Figure 10. Input power vs. mains voltage during standby
The diagram in the following
Figure 11
represents the input power consumption as a
function of the 5 V output current. All other output voltages have no load as in the previous
measurements. It is clearly visible that by decreasing the output current, the input power at
230 Vac still decreases, keeping good efficiency of the circuit.

Even if consumer applications such as set-top boxes or DVDs and digital equipment
generally always have a residual consumption in standby, the board is also capable of
working without any load. In the following
Table 7
the output voltage and power
consumptions measurements during no-load operation are given.
As shown in the table the no-load consumption, thanks to L6566B functionalities, is very low
at both nominal input voltage mains.
