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 input and output capacitors close to the device, using a solid ground plane, and minimizing trace lengths and widths.
To ensure stability, follow the recommended component values and PCB layout, and make sure the input and output capacitors are of high quality and have low ESR. Additionally, the datasheet provides a stability analysis section that can help you determine the stability of the device.
The maximum input voltage is 30V, but it's recommended to derate the input voltage based on the ambient temperature and the device's power dissipation. The datasheet provides a derating curve to help you determine the maximum input voltage for your specific application.
The device is rated for operation up to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. Make sure to follow the thermal design guidelines in the datasheet and consider using a heat sink if necessary.
The power dissipation can be calculated using the formula: Pd = (Vin - Vout) x Iout + (Vin x Iq), where Vin is the input voltage, Vout is the output voltage, Iout is the output current, and Iq is the quiescent current. The datasheet provides more information on how to calculate the power dissipation.
