APPLICATION INFORMATION
layout considerations
As for all switching power supplies, the layout is an important step in the design especially at high peak currents
and switching frequencies. If the layout is not carefully done, the regulator might show stability problems as well
as EMI problems.
Therefore, use wide and short traces for the main current paths as indicted in bold in Figure 16. The input
capacitor should be placed as close as possible to the IC pins as well as the inductor and output capacitor. Place
the bypass capacitor, C3, as close as possible to the FC pin. The analog ground, GND, and the power ground,
PGND, need to be separated. Use a common ground node as shown in Figure 16 to minimize the effects of
ground noise.
