The recommended layout for the TPS60250RTER involves placing the input and output capacitors close to the device, using short and wide traces for the power lines, and separating the analog and digital grounds. A 4-layer PCB with a solid ground plane is also recommended.
The input capacitor should have a low ESR and be rated for the input voltage. A 1-10uF ceramic capacitor is a good choice. The output capacitor should have a low ESR and be rated for the output voltage. A 1-22uF ceramic capacitor is a good choice. The capacitor values can be adjusted based on the specific application requirements.
The TPS60250RTER can handle an input voltage up to 18V, but it is recommended to keep the input voltage below 15V to ensure optimal performance and reliability.
The output voltage of the TPS60250RTER can be adjusted by changing the values of the resistors R1 and R2 in the feedback network. The output voltage can be calculated using the formula: Vout = 1.2V x (R1 + R2) / R2.
The TPS60250RTER can deliver an output current up to 500mA, but it is recommended to keep the output current below 400mA to ensure optimal performance and reliability.
