A 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the component side of the PCB clear of copper to minimize thermal resistance.
Use a high-quality input capacitor (e.g., X5R or X7R) with a capacitance value of at least 10uF, and ensure the input voltage is within the recommended range (4.5V to 18V).
The maximum output current is 3A, but it's recommended to derate the output current to 2.5A for optimal reliability and thermal performance.
Use an external OCP circuit, such as a sense resistor and a comparator, to monitor the output current and shut down the converter in case of an overcurrent event.
Use a low-ESR capacitor (e.g., ceramic or film capacitor) with a capacitance value of at least 10uF and a voltage rating of 25V or higher.
