Typical Application Examples
A 6.5 W NCP1012−Based Flyback Converter
delivering 6.5 W from a universal input. The board uses the
Dynamic Self−Supply and a simplified Zener−type
the following results:
CEE7.5/2
Figure 28 shows a converter built with a NCP1012
The converter built according to Figure 29 layouts, gave
Efficiency at Vin = 100 Vac and Pout = 6.5 W = 75.7%
Efficiency at Vin = 230 Vac and Pout = 6.5 W = 76.5%
