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.
