Typical Performance Characteristics

Typical Flyback Regulator

Applications

Figures 7, 8, 9, 11, 12 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 the table in Figure

13.

For

applications

with

different

output

voltages — requiring the LM2587-ADJ — or different output

configurations that do not match the standard configurations,

refer to the Switchers Made Simple software.
