These application examples show common specification for FA5540/41/42. The same circuitry can be adapted
for FA5540/41/42 except the setting of Vcc pin voltage and the transformer designing that depends on a
switching frequency. (L value and winding ratio of the transformer for FA5541/42 are shown in the figure
below).
