Typical Application Examples
A 6.5 W NCP1015 ? based Flyback converter. (For
evaluation a universal NCP1012 demo ? board can be used)
Figure 27 shows a converter originally built with a
NCP1012 which can be easily used for evaluation of
input range. The board uses the Dynamic Self ? Supply and
a simplified zener ? type feedback. This configuration was
selected for cost reasons and a more precise circuitry can be
used, e.g. based on a TL431:

Figure 27. A NCP1012 ? based Flyback Converter Delivering 6.5 W
The converter built according to Figure 28 layouts, gave
the following results:
? Efficiency at V in = 100 Vac and P out = 6.5 W = 75.7%
? Efficiency at V in = 230 Vac and P out = 6.5 W = 76.5%
