MP2155GQ-Z Frequently Asked Questions (FAQ)

  • The MP2155GQ-Z can handle a maximum input voltage of 18V, but it's recommended to keep it below 15V 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 pin.

  • The MP2155GQ-Z can provide a maximum output current of 1.5A, but it's recommended to keep it below 1.2A for optimal performance and reliability.

  • The output voltage can be adjusted by using a resistive divider network between the output pin and the ground pin. The output voltage is determined by the ratio of the resistors in the divider network.

  • The EN (Enable) pin is used to enable or disable the regulator. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled.
