LAYOUT CONSIDERATIONS FOR THERMAL

PERFORMANCE

For operation at full rated load current, the analog

ground plane must provide adequate heat dissipating

area. A 3 inch by 3 inch plane of 1 ounce copper is

recommended, though not mandatory, depending on

ambient temperature and airflow. Most applications

have larger areas of internal ground plane available,

and the PowerPAD should be connected to the

largest area available. Additional areas on the top or

bottom layers also help dissipate heat, and any area

available should be used when 3 A or greater

operation is desired. Connection from the exposed

area of the PowerPAD to the analog ground plane

layer should be made using 0.013 inch diameter vias

to avoid solder wicking through the vias. Six vias

should be in the PowerPAD area additional vias

located under the device package may be added to

enhance thermal performance. The vias under the

package, but not in the exposed thermal pad area,

can be increased in size to 0.018.
