RT9480GQW 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 and wide traces for the power lines.
  • Ensure that the output capacitor is within the recommended range (22uF to 47uF), and the input capacitor is at least 10uF. Also, keep the feedback resistors (R1 and R2) within the recommended range (1kΩ to 10kΩ).
  • The RT9480GQW can handle up to 28V input voltage, but it's recommended to keep it below 24V for optimal performance and reliability.
  • The output voltage (Vout) can be calculated using the formula: Vout = Vref x (1 + R2/R1), where Vref is the internal reference voltage (1.25V) and R1 and R2 are the feedback resistors.
  • The RT9480GQW can provide up to 3A of output current, but it's recommended to keep it below 2.5A for optimal performance and reliability.
