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 and for the power ground
tracks.

The input capacitor, output capacitor, and the inductor should be placed as close as possible to the IC. Use a
common ground node for power ground and a different one for control ground to minimize the effects of ground
noise. Connect these ground nodes at any place close to one of the ground pins of the IC.
The compensation network as well as the current setting resistors should be placed as close as possible to the
control ground pin of the IC. To lay out the control ground, it is recommended to use short traces as well,
separated from the power ground traces. This avoids ground shift problems, which can occur due to
superimposition of power ground current and control ground current.
