7. Connection of switching ground to system ground, or
any internal ground plane should be single-point. If
the system has an internal system ground plane, a
good way to do this is to cluster vias into a single star
point to make the connection.
8. Route analog ground as a trace tied back to the
LTC4011 GND pin before connecting to any other
ground. Avoid using the system ground plane. A
useful CAD technique is to make analog ground a
separate ground net and use a 0 resistor to connect
analog ground to system ground.
9. A good rule of thumb for via count in a given high
current path is to use 0.5A per via. Be consistent when
applying this rule.

10. If possible, place all the parts listed above on the same
PCB layer.
11. Copper fills or pours are good for all power connec-
tions except as noted above in Rule 3. Copper planes
on multiple layers can also be used in parallel. This
helps with thermal management and lowers trace
inductance, which further improves EMI performance.
12. For best current programming accuracy, provide a
Kelvin connection from RSENSE to SENSE and BAT.
See Figure 14 for an example.
13. It is important to minimize parasitic capacitance on
the TIMER, SENSE and BAT pins. The traces connect-
ing these pins to their respective resistors should be
as short as possible.
