This result largely over passes the today standby
power saving recommendations, meeting the 2005
recommendation limits.
Final price cost of additional components is below then
0.5 US$ and the total price of this power supply remains the
same, compared to typical application circuitry, since all
components dealing with the reconfiguration of secondary
side can be removed.
The basic idea to reach this performance is to power the
IC in the phase, in which it has the lowest power
consumption. At the same time is necessary to stop the
operation of the output stage and leave IC in steady state
conditions. In this case the secondary side output
reconfiguration topology is not used.
Schematic of whole SMPS is presented in Figure 1.
