A 4-layer PCB with a dedicated thermal layer and a solid ground plane is recommended. Ensure a minimum of 10mm clearance around the device for airflow and heat dissipation.
Implement a heat sink with a thermal resistance of 10°C/W or less, and ensure good airflow around the device. Consider using a thermal interface material with a thermal conductivity of 1W/m-K or higher.
A 10uF to 22uF X7R or X5R ceramic capacitor with a voltage rating of 25V or higher is recommended. Place the capacitor as close to the VIN pin as possible.
Use a shielded enclosure, keep the device away from antennas and other EMI-sensitive components, and ensure good grounding and shielding of cables. Implement a common-mode choke or ferrite bead on the input lines if necessary.
The maximum allowed voltage drop is 1V. Ensure that the input voltage rises slowly and monotonically during startup to prevent damage to the device.
