APPLICATIONS INFORMATION
Switching node pin (SW). Keep the sense voltage pins (CAP
and LED) away from the switching node. Place C2 next to
the CAP pin. Always use a ground plane under the switching
regulator to minimize interplane coupling. Recommended
component placement is shown in Figure 7.

Board Layout Considerations
As with all switching regulators, careful attention must
be paid to the PCB layout and component placement. To
prevent electromagnetic interference (EMI) problems,
proper layout of high frequency switching paths is essential.
Minimize the length and area of all traces connected to the
