CS5165A
1. Rapid changes in voltage across parasitic capacitors
and abrupt changes in current in parasitic inductors
are major concerns for a good layout.
2. Keep high currents out of logic grounds.
3. Avoid ground loops as they pick up noise. Use star or
single point grounding. The source of the lower
(synchronous FET) is an ideal point where the input
and output GND planes can be connected.
4. For double?sided PCBs a single large ground plane is
not recommended, since there is little control of
where currents flow and the large surface area can act
as an antenna.
5. Even though double sided PCBs are usually sufficient
for a good layout, four?layer PCBs are the optimum
approach to reducing susceptibility to noise. Use the
two internal layers as the +5.0 V and GND planes, and
the top and bottom layers for the vias.
6. Keep the inductor switching node small by placing
the output inductor, switching and synchronous FETs
close together.

7. The FET gate traces to the IC must be as short,
straight, and wide as possible. Ideally, the IC has to be
placed right next to the FETs.
8. Use fewer, but larger output capacitors, keep the
capacitors clustered, and use multiple layer traces
with heavy copper to keep the parasitic resistance
low.
9. Place the switching FET as close to the +5.0 V input
capacitors as possible.
10. Place the output capacitors as close to the load as
possible.
11. Place the V FB filter resistor in series with theV FB pin
(pin 16) right at the pin.
12. Place the V FB filter capacitor right at the V FB pin
(pin 16).
13. The “Droop” Resistor (embedded PCB trace) has to
be wide enough to carry the full load current.
14. Place the V CC bypass capacitor as close as possible to
the V CC pin.
