Texas Instruments provides a recommended PCB layout in the datasheet, but it's also important to follow general best practices for switching regulator layout, such as keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing trace lengths and widths.
The datasheet provides a list of recommended inductors, but you can also use the following guidelines: choose an inductor with a high saturation current rating, low DC resistance, and a suitable inductance value (typically between 1-10uH). You can also use online inductor selection tools or consult with the inductor manufacturer.
The datasheet specifies a maximum input voltage of 18V, but it's important to note that the device can handle transient voltages up to 22V for short durations (less than 100ms). However, it's recommended to keep the input voltage below 18V for continuous operation.
The output voltage of the TPS5124DBT can be adjusted by changing the resistor divider network connected to the FB pin. The datasheet provides a formula to calculate the required resistor values for a specific output voltage. You can also use online calculators or consult with the datasheet for more information.
The thermal shutdown temperature of the TPS5124DBT is typically around 150°C, but this can vary depending on the specific device and operating conditions. It's recommended to consult the datasheet or contact Texas Instruments for more information.
