Layout Considerations
Switch rise and fall times are kept under 5ns for maximum
efficiency. To minimize radiation, the SW pin and input
bypass capacitor leads (between PVIN and PGND) should
be kept as short as possible. A ground plane should be
used under the switching circuitry to prevent interplane
coupling. The Exposed Pad must be connected to the
ground plane for proper power dissipation. The other
paths contain only DC and/or 1.5MHz tri-wave ripple
current and are less critical.

Qualification, Soft-Start, Remote Sensing and C/10 Indication
With the exception of the input and output filter capacitors
(which should be connected to PGND) all other compo-
nents that return to ground should be connected to
GNDSENS.
