MP4581GN-Z Frequently Asked Questions (FAQs)

  • The MP4581GN-Z can handle input voltages up to 28V, but it's recommended to keep the input voltage below 24V for optimal performance and reliability.
  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, ensure that the output capacitor is placed close to the IC and the input capacitor is placed close to the input voltage source.
  • The MP4581GN-Z can provide up to 3A of output current, but it's recommended to keep the output current below 2.5A for optimal performance and reliability.
  • The output voltage of the MP4581GN-Z can be adjusted by using a resistive divider network between the output and the FB pin. The output voltage can be calculated using the formula: Vout = 0.8V x (R1 + R2) / R2.
  • The EN pin is an enable input that allows the user to turn the regulator on or off. To use it, connect the EN pin to a logic-level signal (0V or 5V) to enable or disable the regulator. When the EN pin is low (0V), the regulator is disabled, and when it's high (5V), the regulator is enabled.
