MPQ2483DQ-AEC1-LF-Z Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A 2-layer or 4-layer PCB with a solid ground plane and thermal vias under the IC is recommended. Keep the input and output capacitors close to the IC and use short, wide traces for the power paths.
• How do I ensure the stability of the output voltage?
  Ensure that the output capacitor has a low ESR and is placed close to the IC. Also, use a minimum of 10uF output capacitance and ensure that the output voltage is within the specified range.
• What is the maximum input voltage that can be applied to the IC?
  The maximum input voltage is 26V, but it's recommended to keep it below 24V for optimal performance and reliability.
• How do I calculate the power dissipation of the IC?
  Use the formula: Pd = (Vin - Vout) x Iout x Efficiency. The efficiency can be obtained from the datasheet or calculated using the formula: Efficiency = (Vout x Iout) / (Vin x Iin).
• What is the recommended input capacitor value and type?
  A 10uF to 22uF X5R or X7R ceramic capacitor is recommended, placed as close to the IC as possible.
