TI recommends a compact layout with minimal trace lengths, using a solid ground plane, and placing the IC close to the input capacitors. Additionally, use a shielded inductor and keep the feedback trace short and away from noisy signals.
Verify that the input voltage is within the recommended range (7.5V to 40V), and the output voltage is within the specified range (1.25V to 37V). Also, ensure the IC is operated within the recommended temperature range (-40°C to 125°C).
Choose an inductor with a high saturation current rating, low DC resistance, and a suitable inductance value (e.g., 10uH to 22uH). Ensure the inductor is shielded to minimize EMI and is compatible with the IC's switching frequency.
Use the recommended compensation network values (R1, R2, C1, and C2) from the datasheet. Adjust these values based on the specific application requirements, such as output voltage and load current. Verify stability using Bode plots or simulation tools.
Ensure good thermal conduction between the IC and the PCB. Use a thermal pad or a heat sink if necessary. Keep the IC away from heat sources, and ensure good airflow. Monitor the junction temperature (TJ) and ensure it remains below the maximum rating (150°C).
