Texas Instruments provides a recommended PCB layout in the datasheet, but it's also important to follow general high-frequency layout guidelines, such as keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing trace lengths and widths.
The selection of the inductor depends on the output current, output voltage, and switching 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.
The TPS62361BYZHT is rated for operation up to 125°C, but the maximum ambient temperature for reliable operation depends on the specific application and the thermal design of the system. It's recommended to derate the device's power dissipation and ensure proper thermal management to ensure reliable operation.
To ensure stability, follow the recommended component values and PCB layout guidelines in the datasheet. Additionally, ensure that the output capacitor has a low equivalent series resistance (ESR) and that the input capacitor is properly bypassed. You can also use simulation tools to verify the stability of your design.
The recommended input capacitor type is a ceramic capacitor with a value of 10uF to 22uF. The capacitor should have a low ESR and be rated for the input voltage. TI recommends using a capacitor with an X5R or X7R dielectric.
