Typical Boost Regulator Applications
Figure 36and Figures 38, 39and Figure 40show 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
