Texas Instruments provides a recommended PCB layout in the application note SLVAE03, which includes guidelines for thermal vias, copper pours, and component placement to ensure optimal thermal performance.
The input capacitor selection depends on the input voltage, output voltage, and output current. TI recommends using a low-ESR capacitor with a value between 10uF to 22uF, and a voltage rating of at least 1.5 times the input voltage. Refer to the application note SLVAE03 for more details.
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 guideline, TI recommends keeping the ambient temperature below 85°C for most applications.
To ensure EMC, follow the guidelines in the TI application note SLVAE03, which includes recommendations for PCB layout, component selection, and shielding. Additionally, consider using a common-mode choke and/or a ferrite bead on the input lines to reduce EMI.
The output capacitor selection depends on the output voltage, output current, and desired ripple voltage. TI recommends using a low-ESR capacitor with a value between 10uF to 47uF, and a voltage rating of at least 1.5 times the output voltage. Refer to the application note SLVAE03 for more details.
