A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the high-frequency traces short and away from the edges of the board. Use a common mode choke and ferrite beads to filter the input and output lines.
To minimize standby power consumption, ensure that the EN pin is driven low during shutdown. Also, disconnect the input voltage from the device when not in use. Additionally, use a low-quiescent-current voltage regulator for the VCC pin.
The maximum allowed voltage on the VIN pin is 30V, but it's recommended to keep it below 28V to ensure reliable operation and to prevent damage to the device.
Use a voltage supervisor or a reset IC to monitor the input voltage and reset the FDP8860 if it falls outside the recommended operating range. You can also add a TVS diode or a zener diode to clamp the input voltage.
Use a thermal pad or a heat sink to dissipate heat from the device. Ensure good airflow around the device and avoid blocking the airflow with components or obstacles. You can also use thermal interface materials to improve heat transfer.
