MP4570GF datasheet by Monolithic Power Systems

MP4570GF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the MP4570GF can handle?
  The MP4570GF can handle input voltages up to 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
• How do I optimize the layout for the MP4570GF to minimize EMI?
  To minimize EMI, keep the input and output capacitors close to the IC, use a solid ground plane, and keep the high-current paths short and direct. Also, consider using a shielded inductor and orienting the IC to minimize radiation.
• What is the recommended output capacitor type and value for the MP4570GF?
  A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended for the output capacitor. X5R or X7R dielectrics are suitable for most applications.
• How do I adjust the output voltage of the MP4570GF?
  The output voltage can be adjusted by changing the resistor divider ratio between the FB pin and the output voltage. A higher resistor value will increase the output voltage, while a lower value will decrease it.
• What is the maximum output current that the MP4570GF can deliver?
  The MP4570GF can deliver up to 3A of output current, but it's recommended to derate the current based on the input voltage, output voltage, and ambient temperature to ensure reliable operation.
