Texas Instruments recommends a thermal pad on the bottom of the package, connected to a copper plane on the PCB to dissipate heat. A minimum of 2oz copper thickness is recommended, and the thermal pad should be connected to a ground plane to reduce thermal resistance.
To ensure reliable operation at high temperatures, it's essential to follow the recommended operating conditions, including voltage and current ratings. Additionally, consider using thermal management techniques such as heat sinks, thermal interfaces, and airflow to keep the device within its specified temperature range.
Although the datasheet specifies a maximum input voltage of 15V, it's recommended to limit the input voltage to 12V to ensure reliable operation and prevent damage to the device.
To minimize EMI and noise issues, use proper PCB layout techniques, such as separating analog and digital grounds, using decoupling capacitors, and shielding sensitive signals. Additionally, consider using EMI filters or common-mode chokes to reduce noise and electromagnetic interference.
The recommended output filter capacitor value depends on the specific application and desired output ripple. A general guideline is to use a capacitor with a value between 10uF to 47uF, with a voltage rating of at least 25V. However, it's essential to consult the datasheet and application notes for specific guidance.
