PC Board Layout Checklist
When laying out the printed circuit board, the following
checklist should be used to ensure proper operation of the
LTC3410B. These items are also illustrated graphically in
Figures 4 and 5. Check the following in your layout:
1. The power traces, consisting of the GND trace, the SW
trace and the V IN trace should be kept short, direct and
wide.
2. Does the V FB pin connect directly to the feedback
resistors? The resistive divider R1/R2 must be con-
nected between the (+) plate of C OUT and ground.
3. Does the (+) plate of C IN connect to V IN as closely as
possible? This capacitor provides the AC current to the
internal power MOSFETs.
4. Keep the (–) plates of C IN and C OUT as close as possible.
5. Keep the switching node, SW, away from the sensitive
V FB node.
