Figure 20. Standard Test Circuits and Layout Guides  
As in any switching regulator, layout is very important. Rapidly switching currents associated with wiring  
inductance can generate voltage transients which can cause problems. For minimal inductance and ground  
loops, the wires indicated by heavy lines should be wide printed circuit traces and should be kept as short  
as possible. For best results, external components should be located as close to the switcher lC as possible  
using ground plane construction or single point grounding.  
If open core inductors are used, special care must be taken as to the location and positioning of this type of  
inductor. Allowing the inductor flux to intersect sensitive feedback, lC groundpath and COUT wiring can cause  
problems.  
When using the adjustable version, special care must be taken as to the location of the feedback resistors and  
the associated wiring. Physically locate both resistors near the IC, and route the wiring away from the inductor,  
especially an open core type of inductor. (See Application Information section for more information.)
