Typical Application Examples
A 6.5 W NCP1012Based Flyback Converter
Figure 28 shows a converter built with a NCP1012
delivering 6.5 W from a universal input. The board uses the
Dynamic SelfSupply and a simplified Zenertype
feedback. This configuration was selected for cost reasons
and a more precise circuitry can be used, e.g. based on a
TL431:

The converter built according to Figure 29 layouts, gave
the following results:
Efficiency at Vin = 100 Vac and Pout = 6.5 W = 75.7%
Efficiency at Vin = 230 Vac and Pout = 6.5 W = 76.5%
