operation
When laying out multiple LTC4266A devices, group the
four sets of port MOSFET and sense resistor with their
respective LTC4266A as shown in Figure 5. Each LTC4266A
has its own copper fill area on the surface that connects
to the VEE plane with multiple large vias. The net effect
is to reduce the layout problem down to 4-port groups;
this arrangement is expandable to any number of ports.
