3.2 ValueLine Reference Design
Design Note DN025
The integrated inductor ValueLine Reference designs offer the lowest possible cost. The
schematics are similar to those shown in Figure 2 and Figure 3 with the exception that the
inductors have been integrated into the PCB. This gives a cost advantage but also means
that the reference design must be strictly followed by using the same PCB thickness
otherwise the performance will change.
The integrated inductor ValueLine reference designs have the lowest cost but are also the
largest in size.
