MPQ4470GL-AEC1-Z - Monolithic Power Systems (MPS)

MPQ4470GL-AEC1-Z Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the MPQ4470GL-AEC1-Z can handle?
  The maximum input voltage is 26V, but it's recommended to keep it below 24V for reliable operation.
• How do I ensure the stability of the output voltage?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, use a low-ESR ceramic capacitor for the output filter capacitor.
• What is the maximum output current that the MPQ4470GL-AEC1-Z can provide?
  The maximum output current is 3A, but it's recommended to keep it below 2.5A for reliable operation and to prevent overheating.
• How do I calculate the power dissipation of the MPQ4470GL-AEC1-Z?
  The power dissipation can be calculated using the formula: Pd = (Vin - Vout) x Iout. Make sure to consider the thermal resistance and junction temperature to ensure reliable operation.
• What is the purpose of the EN pin, and how do I use it?
  The EN (enable) pin is used to turn the regulator on or off. Connect it to a logic high (e.g., 3.3V or 5V) to enable the regulator, and connect it to a logic low (e.g., GND) to disable it.
