Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the input and output traces as short as possible. Additionally, use a common mode choke and ferrite beads to filter out high-frequency noise.
Use a high-quality, low-ESR capacitor (e.g., 10uF ceramic) as close as possible to the VIN pin, and a 1uF capacitor on the VOUT pin. Ensure the power supply can provide the required current, and consider adding a voltage regulator if necessary.
Although the datasheet specifies a maximum input voltage of 12V, it's recommended to limit the input voltage to 10V to ensure reliable operation and prevent damage to the device.
Use the VOUT pin and an external resistor divider network to set the desired output voltage. The datasheet provides a formula to calculate the required resistor values.
The device has a thermal derating of 12mW/°C above 25°C. Ensure good airflow, use a heat sink if necessary, and follow the recommended PCB layout and thermal design guidelines to minimize thermal resistance.
