TPS61131PW Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS61131PW is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
  • To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, including the use of a 10uF ceramic capacitor at the input and a 22uF ceramic capacitor at the output. Additionally, keep the feedback loop as short as possible and avoid using long traces or wires.
  • The minimum ESR required for the output capacitor is 0.1 ohms. Using a capacitor with a lower ESR can cause instability and affect the regulator's performance.
  • Yes, a ceramic capacitor can be used as the output capacitor, but it's recommended to use a capacitor with a high ripple current rating and a low ESR. X5R or X7R ceramic capacitors are good options. However, it's essential to follow the recommended layout and component selection guidelines to ensure stability.
  • The output voltage of the TPS61131PW can be calculated using the following formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (1.21V), R1 is the feedback resistor, and R2 is the divider resistor. Make sure to use the correct values for R1 and R2 to achieve the desired output voltage.
