Typical Performance Characteristics
Typical Boost Regulator Applications
Figures 33, 35 through Figure 37 show four typical boost
applications — one fixed and three using the adjustable ver-
sion of the LM2586. Each drawing contains the part num-
ber(s) and manufacturer(s) for every component. For the
fixed 12V output application, the part numbers and manufac-
turers’ names for the inductor are listed in a table in
Figure
34. For applications with different output voltages, refer to
the
Switchers Made Simple software.
