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 using a solid ground plane, minimizing trace lengths, and using vias to connect the input and output capacitors to the ground plane.
To ensure stability, follow the datasheet's guidelines for output capacitor selection, and make sure the output capacitor's ESR is within the recommended range. Additionally, ensure the input voltage is within the recommended range, and the input capacitor is properly sized and placed close to the IC.
The maximum ambient temperature for the LM2748MTCX/NOPB is 125°C, but it's recommended to derate the output current and input voltage to ensure reliable operation at high temperatures.
Yes, the LM2748MTCX/NOPB is qualified for automotive and high-reliability applications, but it's recommended to follow Texas Instruments' guidelines for reliability and qualification, and to consult with their application engineers for specific requirements.
Use a oscilloscope to measure the input and output voltages, and check for signs of oscillation or ringing. Verify the PCB layout and component selection meet the datasheet's recommendations, and consult the datasheet's troubleshooting section for common issues and solutions.
