Why use the flyback topology? Flyback power supplies use the
least number of components. At power levels below 75 watts, total flyback component cost is lower when compared to other
techniques.
Between 75 and 100 Watts, increasing voltage and
current stresses cause flyback component cost to increase
significantly. At higher power levels, topologies with lower
voltage and current stress levels (such as the forward converter)
may be more cost effective even with higher component counts.
