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 parasitic inductance.
To ensure stability, make sure to follow the recommended component values and PCB layout, and also ensure that the input and output capacitors are of high quality and have low ESR. Additionally, the datasheet provides a stability analysis section that can help you determine the stability of the device.
The maximum input voltage is not explicitly stated in the datasheet, but it's recommended to keep the input voltage below 6V to ensure reliable operation and prevent damage to the device.
The LM3691TLX-1.8/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at higher temperatures to ensure reliable operation. Additionally, the device's performance may degrade at high temperatures, so it's recommended to consult the datasheet and perform thermal analysis to ensure the device meets the required specifications.
To troubleshoot issues, start by checking the input voltage, output voltage, and output current to ensure they are within the recommended specifications. Then, check the PCB layout and component values to ensure they match the recommended values. If the issue persists, consult the datasheet's troubleshooting section or contact Texas Instruments' technical support for further assistance.
