Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the input and output traces as short as possible. Additionally, it's recommended to use a common mode choke or a ferrite bead to filter out high-frequency noise.
To ensure stability, make sure to follow the recommended compensation network values and layout guidelines. Also, ensure that the input and output capacitors are of high quality and have low ESR. Additionally, it's recommended to add a small resistor (e.g. 10 ohms) in series with the output capacitor to prevent oscillation.
The maximum input voltage that the LMV1090TLX/NOPB can handle is 12V, but it's recommended to keep the input voltage below 10V to ensure reliable operation and to prevent damage to the device.
The LMV1090TLX/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at high temperatures to ensure reliable operation. Additionally, it's recommended to use a heat sink to keep the device temperature below 100°C.
To troubleshoot issues with the LMV1090TLX/NOPB, start by checking the input and output voltages, and ensure that the device is properly biased. Use an oscilloscope to check for oscillations or noise on the output. Also, check the PCB layout and ensure that it follows the recommended guidelines. If the issue persists, consult the Texas Instruments support team or a qualified engineer for further assistance.
