Typical Boost Regulator Applications

Figure 36 and Figures 38, 39 and Figure 40 show four typical

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, re-

fer to the

Switchers Made Simple software.

Figure 37 contains a table of standard inductors, by part number and corresponding manufacturer, for the fixed output regulator

of

Figure 36.
