A thermal pad is recommended under the package to improve heat dissipation. A minimum of 2oz copper thickness and a thermal relief pattern are recommended. The PCB should also have a solid ground plane to reduce thermal resistance.
Ensure that the device is operated within the recommended junction temperature range (TJ) of -40°C to 150°C. Use a heat sink or thermal interface material to reduce the thermal resistance between the device and the heat sink. Also, ensure good airflow around the device.
A 10uF to 22uF X5R or X7R ceramic capacitor is recommended for the input capacitor. The capacitor should be placed as close to the device as possible to minimize parasitic inductance.
Use a shielded inductor, keep the input and output traces as short as possible, and use a common-mode choke to reduce EMI. Also, ensure that the PCB layout is designed to minimize radiation and conduction of EMI.
