Applications
boost applications) — one fixed and three using the adjust-
able version of the LM2587. Each drawing contains the part
number(s) and manufacturer(s) for every component. For
the fixed 12V output application, the part numbers and
manufacturers’ names for the inductor are listed in a table in
Figure 40. For applications with different output voltages,
refer to the Switchers Made Simple software.
Figure 37 contains a table of standard inductors, by part
number and corresponding manufacturer, for the fixed out-
put regulator of Figure 36.
