Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-frequency PCB design guidelines, such as keeping the power traces short and wide, using a solid ground plane, and minimizing signal loop areas.
The output inductor selection depends on the output voltage, current, and frequency. TI provides an inductor selection guide in the datasheet, but you can also use online inductor selection tools or consult with an inductor manufacturer to find the right part for your design.
While the datasheet specifies an operating temperature range of -40°C to 125°C, the maximum ambient temperature for reliable operation depends on the specific application and cooling conditions. As a general rule, it's recommended to keep the ambient temperature below 85°C for most applications.
To ensure EMC compliance, follow proper PCB layout and design guidelines, use shielding and filtering components as needed, and perform EMC testing according to relevant standards (e.g., CISPR 22, EN 55022). TI also provides EMC design guidelines in the datasheet.
The recommended input capacitor type is a low-ESR ceramic capacitor (e.g., X5R or X7R) with a value of 10-22 μF. The exact value depends on the input voltage, current, and frequency, as well as the specific application requirements.
