PC Board Layout Checklist
When laying out the printed circuit board, the following
checklist should be used to ensure proper operation of the
LTC3416. Check the following in your layout.
1. A ground plane is recommended. If a ground plane layer
is not used, the signal and power grounds should be
segregated with all small-signal components returning
to the SGND pin at one point which is then connected to
the PGND pin close to the LTC3416.
2. Connect the (+) terminal of the input capacitor(s), C IN ,
as close as possible to the PV IN pin. This capacitor
provides the AC current into the internal power MOSFETs.

3. Keep the switching node, SW, away from all sensitive
small-signal nodes.
4. Flood all unused areas on all layers with copper. Flood-
ing with copper will reduce the temperature rise of
power components. You can connect the copper areas
to any DC net (PV IN , SV IN , V OUT , PGND, SGND or any
other DC rail in your system).
5. Connect the V FB pin directly to the feedback resistors.
The resistor divider must be connected between V OUT
and SGND.
