MP4026GJ-Z Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the MP4026GJ-Z?
  The maximum input voltage that can be applied to the MP4026GJ-Z is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
• How do I ensure the stability of the output voltage in the MP4026GJ-Z?
  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.
• What is the maximum output current that the MP4026GJ-Z can deliver?
  The maximum output current that the MP4026GJ-Z can deliver is 2A, but it's recommended to keep it below 1.5A for optimal performance and reliability.
• How do I adjust the output voltage of the MP4026GJ-Z?
  The output voltage of the MP4026GJ-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.
• What is the purpose of the EN pin in the MP4026GJ-Z?
  The EN (Enable) pin is used to enable or disable the regulator. When the EN pin is pulled high, the regulator is enabled, and when it's pulled low, the regulator is disabled.
