9.2.1 Typical Flyback Regulator Applications

Figure 25 through Figure 30 show six typical flyback applications, varying from single output to triple output. Each drawing contains the part number(s) and manufacturer(s) for every component except the transformer. For the transformer part numbers and manufacturers' names, see Table 2. For applications with different output voltages—requiring the LM2588-ADJ—or different output configurations that do not match the standard configurations, refer to the Switchers Made Simple software.
