TPS65581PWPR Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the IC, and use short, wide traces for the power lines.
  • Ensure that the output capacitor has a low ESR, and the input capacitor is at least 10uF. Also, add a 1-2nF capacitor between the VCC and GND pins to filter high-frequency noise.
  • The maximum input voltage is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
  • The TPS65581PWPR is rated for operation up to 125°C, but the junction temperature should be kept below 150°C to ensure reliability. Use a heat sink or thermal pad to dissipate heat if necessary.
  • Use the formulas provided in the datasheet: Vout = (R1/R2) * (Vin - Vref) and Iout = (Vout - Vref) / Rload. Ensure that the output voltage and current do not exceed the maximum ratings.
