Application Information (cont.)
Thermal Considerations
When operating the device at high ambient temperatures, or when driving maximum load current, care must be taken to avoid exceeding the
package power dissipation limits. The graph below gives details for power derating. This assumes the device to be mounted on a 25mm
PCB with 1oz copper standing in still air.

Maximum Power Dissipation
Note that the device power dissipation will most often be a maximum at minimum supply voltage. It will also increase if the efficiency of the
circuit is low. This may result from the use of unsuitable coils, or excessive parasitic output capacitance on the switch output.
In order to maximize the thermal capabilities of the DFN3030-6 and the SO-8EP packages thermal vias should be incorporated into the PCB.
See figures 7 and 8 for examples used in the ZXLD1366 evaluation boards.
