A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output tracks as short as possible and use a common mode choke to reduce EMI.
Ensure the input voltage is within the recommended range (4.5V to 18V) and the enable pin is properly biased (high or low) according to the application requirements.
The maximum current rating of the RHFL7913KPA1 is 1.3A, but it's recommended to derate the current to 1A for reliable operation.
Use a voltage supervisor or a voltage monitor IC to detect overvoltage and undervoltage conditions and shut down the device if necessary. Also, consider adding a TVS diode for overvoltage protection.
Use a thermal pad or a heat sink to dissipate heat. Ensure good airflow around the device and avoid blocking the airflow. Consider using a thermal interface material (TIM) to improve heat transfer.
