The recommended layout for the TPS3513D involves placing the input capacitors close to the VIN pin, using a solid ground plane, and keeping the output capacitors close to the VOUT pin. Additionally, it's recommended to use a separate power plane for the input and output to minimize noise coupling.
The choice of input and output capacitors depends on the specific requirements of your application. For the input capacitor, a low-ESR ceramic capacitor with a value between 1uF to 10uF is recommended. For the output capacitor, a low-ESR ceramic capacitor with a value between 1uF to 22uF is recommended. The capacitor values should be chosen based on the output voltage, output current, and desired ripple voltage.
The TPS3513D can handle input voltages up to 15V, but it's recommended to operate within the specified input voltage range of 2.7V to 12V for optimal performance and reliability.
The output voltage of the TPS3513D can be adjusted by using a resistive divider network between the VOUT pin and the GND pin. The output voltage is determined by the ratio of the resistors in the divider network. The recommended resistor values are R1 = 10kΩ and R2 = 2.2kΩ for a 3.3V output voltage.
The TPS3513D can deliver up to 1.5A of output current, but it's recommended to operate within the specified output current range of 0.5A to 1.2A for optimal performance and reliability.
