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 that the output capacitor is of high quality and has a low ESR. Also, add a 10nF capacitor in parallel with the output capacitor to improve stability.
The maximum ambient temperature for reliable operation is 85°C. However, it's recommended to derate the output current at higher temperatures to ensure reliability.
Yes, but ensure that the module is properly secured to the PCB and that the PCB is designed to withstand the vibrations. Also, consider adding additional mechanical support to the module.
Use an oscilloscope to check the input and output waveforms. Check for proper input voltage, output voltage, and current. Also, check for any signs of overheating or physical damage.
