adp3339 rev. a | page 11 of 12 use the following general guidelines when designing printed circuit boards: 1. keep the output capacitor as close to the output and ground pins as possible. 2. keep the input capacitor as close to the input and ground pins as possible. 3. pc board traces with larger cross sectional areas remove more heat from the adp3339. for optimum heat transfer, specify thick copper and use wide traces. 4. the thermal resistance can be decreased by adding a copper pad under the adp3339, as shown in figure 22b. 5. if possible, utilize the adjacent area to add more copper around the adp3339. connecting the copper area to the output of the adp3339, as shown in figure 22c, is best, but thermal performance will be improved even if it is connected to other pins. 6. use additional copper layers or planes to reduce the thermal resistance. again, connecting the other layers to the output of the adp3339 is best, but is not necessary. when connecting the output pad to other layers, use multiple vias.
