Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-frequency PCB design guidelines, such as keeping the input and output traces short and away from each other, using a solid ground plane, and minimizing vias and thermal reliefs.
To ensure stability, follow the recommended component values and PCB layout, and make sure the input and output capacitors are properly selected and placed. Additionally, the datasheet provides a stability analysis section that can help you determine the stability of the device.
The LM2744MTCX/NOPB is rated for operation up to 125°C, but the maximum ambient temperature for reliable operation depends on the specific application and the device's power dissipation. It's recommended to follow the thermal design guidelines in the datasheet and ensure proper heat sinking and airflow.
While it's possible to use a different inductor value or type, it's not recommended as it may affect the device's performance and stability. The recommended inductor values and types are specified in the datasheet for a reason, and deviating from them may require additional design and testing efforts.
To troubleshoot issues, start by verifying the input voltage, output voltage, and component values. Check for proper PCB layout, soldering, and component placement. Use an oscilloscope to measure the output voltage and ripple, and consult the datasheet's troubleshooting section for guidance.
