A good layout practice is to keep the input and output capacitors close to the device, and to use a solid ground plane to reduce noise. Additionally, it is recommended to keep the feedback resistors close to the device and to use a separate analog ground plane to minimize noise coupling.
The output capacitor should be chosen based on the output voltage and current requirements. A general rule of thumb is to use a capacitor with a capacitance value of at least 10uF and an ESR of less than 100mΩ. X5R or X7R ceramic capacitors are good options.
The TPS60111PWP can handle input voltages up to 18V, but it is recommended to keep the input voltage below 15V to ensure reliable operation and to prevent overheating.
The output voltage of the TPS60111PWP can be adjusted by changing the ratio of the feedback resistors R1 and R2. The output voltage is calculated using the formula Vout = 1.25V x (1 + R2/R1).
The TPS60111PWP can deliver up to 1A of output current, but it is recommended to keep the output current below 800mA to ensure reliable operation and to prevent overheating.
