MP4688DN-LF-Z datasheet by Monolithic Power Systems

MP4688DN-LF-Z Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the MP4688DN-LF-Z can handle?
  The maximum input voltage is 24V, but it's recommended to keep it below 20V for optimal performance and reliability.
• How do I ensure the stability of the output voltage?
  To ensure stability, make sure to use the recommended output capacitor values and types, and keep the output voltage within the specified range. Also, ensure that the input voltage is within the recommended range and the input capacitor is properly sized.
• What is the maximum output current that the MP4688DN-LF-Z can provide?
  The maximum output current is 8A, but it's recommended to keep it below 6A for optimal performance and reliability.
• How do I calculate the output voltage of the MP4688DN-LF-Z?
  The output voltage can be calculated using the formula: Vout = (R1 / R2) * (1.25V), where R1 and R2 are the resistors used in the feedback network.
• What is the purpose of the EN pin on the MP4688DN-LF-Z?
  The EN (enable) pin is used to turn the device on or off. When the EN pin is high, the device is enabled, and when it's low, the device is disabled.
