Figure 6. Use of thermal & noise suppression vias.
Recommendation 1:
Input and output filter
capacitors should be placed as close to the
EN5366QI package as possible to reduce EMI
from input and output loop currents.
This
reduces the physical area of the Input and
Output AC current loops.
Recommendation 2
: Place a slit in the
input/output capacitor ground copper starting
just below the common connection point of the
device GND pins as shown in figures 5 and 6.
Recommendation 3
: The large thermal pad
underneath the component must be connected
to the system ground plane through as many
vias as possible. The drill diameter of the vias
should be less than 0.33mm, and the vias must
have at least 1 oz. copper plating on the inside
wall, making the finished hole size around
0.26mm. This connection provides the path for
heat dissipation from the converter. Please see
figures 6, 7, and 8.
Recommendation
4
: Multiple small vias
should be used to connect ground terminal of
the input capacitor and output capacitors to the
system ground plane as shown in figure 6.
These vias can be the same size as the
thermal vias discussed in recommendation 3.
Recommendation
5:
The system ground
plane referred to in recommendations 3 and 4
should be the first layer immediately below the
surface layer. This ground plane should be
continuous and un-interrupted below the
converter and the input/output capacitors
shown in figure 6.
Recommendation 6
: As with any switch-mode
DC/DC converter, do not run sensitive signal or
control
lines
underneath
the
converter
package.
Please refer to the Gerber files and
summarized layout notes available on the
Enpirion website www.enpirion.com for more
layout details.
NOTE
: Figures 5 and 6 show only the critical
components and traces for a minimum footprint
layout. ENABLE, Vout-programming, and
other small signal pins need to be connected
and routed according to the specific
application.
