MPQ2167GD-Z - Monolithic Power Systems (MPS)

MPQ2167GD-Z Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the MPQ2167GD-Z?
  The maximum input voltage that can be applied to the MPQ2167GD-Z is 26V, although it's recommended to keep it below 24V for reliable operation.
• How do I ensure the MPQ2167GD-Z is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component selection guidelines, including the use of a 10uF ceramic capacitor at the input and a 22uF ceramic capacitor at the output. Also, keep the feedback loop as short as possible and avoid using long traces.
• What is the minimum ESR required for the output capacitor?
  The minimum ESR required for the output capacitor is 0.01Ω. Using a capacitor with a lower ESR can cause instability and affect the regulator's performance.
• Can I use the MPQ2167GD-Z in a high-temperature environment?
  The MPQ2167GD-Z is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation. Consult the datasheet for more information on thermal derating.
• How do I calculate the power dissipation of the MPQ2167GD-Z?
  The power dissipation of the MPQ2167GD-Z can be calculated using the formula: Pd = (Vin - Vout) x Iout + (Vin x Iq), where Vin is the input voltage, Vout is the output voltage, Iout is the output current, and Iq is the quiescent current.
