Flyback Regulator Operation
Typical Flyback Regulator Applications
Figure 7 through Figure 12 show six typical flyback applica-
tions, varying from single output to triple output. Each draw-
ing contains the part number(s) and manufacturer(s) for ev-
ery component except the transformer. For the transformer
part numbers and manufacturers names, see the table in
