MP2403DN-LF Frequently Asked Questions (FAQs)

  • The MP2403DN-LF 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, keep the output voltage within the recommended range of 0.8V to 5.5V.
  • The MP2403DN-LF can provide a maximum output current of 3A, but it's recommended to keep it below 2.5A for optimal performance and reliability.
  • The output voltage can be adjusted by using a resistive divider network between the FB pin and the output voltage. The recommended resistors are R1 = 10kohm and R2 = 2.2kohm for a 3.3V output voltage.
  • 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.
