Layout and Grounding
Considerations
High frequency switching and large peak currents means
PCB design for DC-DC converters requires careful
consideration. As a general rule place the DC-DC converter
circuitry well away from any sensitive RF or analog compo-
nents. The layout of the DC-DC converters and its external
components are also based on some simple rules to minimize
EMI and output voltage ripple.
Layout
1.
Place all power components, ILC6363, inductor, input
capacitor and output capacitor as close together as
possible.
2.
Keep the output capacitor as close to the ILC6363 as
possible with very short traces to the V
OUT
and GND
pins. Typically it should be within 0.25 inches or 6mm.
3.
Keep the traces for the power components wide,
typically >50mil or 1.25mm.
4.
Place the external networks for LBI and VFB close to
the ILC6363, but away from the power components as
far as possible.
Grounding
1.
Use a star grounding system with separate traces for
the power ground and the low power signals such as
LBI/SD and VFB. The star should radiate from where
the power supply enters the PCB.
2.
On multilayer boards use component side copper for
grounding around the ILC6363 and connect back to a
quiet ground plane using vias.
