The Golden Rule of Board Layout for SMPS (Download)
This article explains the basis for achieving an optimized board layout, a critical aspect in the design of switch-mode power supplies (SMPS). A good layout ensures stable functioning of the switching regulator and minimizes radiated interference as well as conducted interference (EMI)—widely known by electronics developers. However, what’s not generally known is how an optimized board layout for a switch-mode power supply should look.
