A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the high-current paths short and use a common mode choke to reduce EMI.
Use a thermal pad on the bottom of the package, and ensure good airflow around the device. A heat sink can also be used to improve thermal performance.
A 10uF to 22uF X5R or X7R ceramic capacitor is recommended for the input capacitor, placed as close to the device as possible.
Use a voltage supervisor or a power-on reset circuit to monitor the input voltage and reset the device if it falls outside the recommended operating range.
A second-order LC filter with a 1uH inductor and a 10uF capacitor is recommended to filter the output voltage and reduce ripple.
