MP24833-AGN - Monolithic Power Systems (MPS)

MP24833-AGN Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the IC, and use short, wide traces for the power paths.
• How do I ensure stability and prevent oscillations?
  Ensure that the output capacitor has a low ESR, and the input capacitor has a high capacitance. Also, add a small ceramic capacitor (e.g., 10nF) between the VIN and GND pins to filter out high-frequency noise.
• What is the maximum input voltage that can be applied to the VIN pin?
  The maximum input voltage is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
• Can I use a different inductor value or type?
  Yes, but ensure that the inductor has a high saturation current rating and a low DCR. The recommended inductor value is 2.2uH, but you can use a different value as long as it meets the required inductance and current rating.
• How do I adjust the output voltage?
  The output voltage can be adjusted by changing the resistor divider ratio between the FB pin and the output voltage. Use the formula in the datasheet to calculate the required resistor values.
