Layout Considerations
As for all switching power supplies, the layout is an
important step in the design, especially at high peak
currents and high switching frequencies.
If the
layout is not carefully done, the regulator could
show stability problems as well as EMI problems.
Therefore, use wide and short traces for the main
current path as indicated in bold in Figure 4.
The
input capacitor, output capacitor and the inductor
should be placed as close to the IC as possible.
Use a common ground node as shown in Figure 4
to minimize the effects of ground noise.
The
feedback divider should be placed as close to the IC
as possible.
