adequate for most applications. Connect the V
REF
pin
directly to SV
IN
. Connecting the V
FB
pin directly to V
OUT
will set the output voltage equal to one-half of the voltage
on the V
REF
pin. The complete circuit for this design
example is illustrated in Figure 3.
PC Board Layout Checklist
When laying out the printed circuit board, the following
checklist should be used to ensure proper operation of the
LTC3413. 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 LTC3413.
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 V
OUT
pin.
