Texas Instruments recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to ensure optimal thermal performance.
To ensure reliable operation in high-temperature environments, it is recommended to derate the device's power dissipation according to the thermal derating curve provided in the datasheet, and to ensure good thermal conduction to the PCB and heat sink.
The recommended input capacitor value is 10uF to 22uF, and a low-ESR ceramic capacitor (X5R or X7R dielectric) is recommended to ensure stable operation and minimize voltage ripple.
To troubleshoot issues with the device's output voltage regulation, check the input voltage, output load, and PCB layout for any anomalies or noise sources. Also, verify that the device is properly configured and that the output capacitor values are within the recommended range.
