Typical Boost Regulator Applications
Figure 49 through Figure 52 show four typical boost applications—one fixed and three using the adjustable
version of the LM2586. 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
Table 3. For applications with different output voltages, refer to the Switchers Made Simple software.
