Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general guidelines for high-frequency PCB design, such as using a solid ground plane, minimizing trace lengths, and using bypass capacitors to reduce noise and oscillations.
To ensure stability, follow the recommended compensation network values and layout, and make sure the output capacitor is properly selected and placed. Additionally, ensure that the input and output voltage rails are properly decoupled, and the device is operated within its recommended operating conditions.
The maximum input voltage rating for the LM9036QMMX-5.0/NOPB is 6.5V, but it's recommended to operate the device within the recommended input voltage range of 4.5V to 5.5V for optimal performance and reliability.
The LM9036QMMX-5.0/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and power dissipation at higher temperatures to ensure reliability and prevent thermal shutdown.
Start by checking the input voltage, output voltage, and output current to ensure they are within the recommended operating conditions. Check the PCB layout and component values to ensure they match the recommended design. Use an oscilloscope to check for oscillations or noise on the output, and use a thermal camera or thermometer to check for excessive heat.
