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.
The choice of input and output capacitors depends on the specific application and operating conditions. In general, X7R or X5R ceramic capacitors with a voltage rating of at least 2x the input voltage are recommended. The output capacitor should be chosen based on the desired output ripple and ESR requirements.
The LM6584MA/NOPB has an operating temperature range of -40°C to 125°C, but the maximum ambient temperature range depends on the specific application and thermal design. It's recommended to follow the thermal design guidelines in the datasheet and ensure that the device is properly heat-sinked.
Yes, the LM6584MA/NOPB is qualified for automotive and high-reliability applications, but it's recommended to follow the specific requirements and guidelines for these applications, such as AEC-Q100 and ISO 26262. Additionally, Texas Instruments provides a range of automotive-qualified and high-reliability versions of the LM6584MA/NOPB.
Common issues with the LM6584MA/NOPB can often be troubleshooted by checking the input and output voltage levels, ensuring proper PCB layout and component selection, and verifying that the device is properly heat-sinked. Texas Instruments also provides a range of application notes and technical resources to help troubleshoot and optimize the performance of the LM6584MA/NOPB.
