COMMON APPLICATIONS

Table 9 through Table 11 list a number of common component

selections for typical VIN and VOUT conditions. These have been

bench tested and provide an off the shelf solution. Note that when

pairing a boost and inverting regulator bill of materials, choose

the same VIN and switching frequency. To optimize components

for an application, it is recommend to use the ADIsimPower

toolset.

Figure 47 shows the schematic referenced by Table 9 through

Table 11 with example component values for +5 V to ±15 V

generation. Table 9 shows the components common to all of the

VIN and VOUT conditions.
