MP9943GQ-Z Frequently Asked Questions (FAQs)

  • The MP9943GQ-Z can handle input voltages up to 24V, but it's recommended to keep it below 18V for optimal performance and reliability.
  • 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 wide. Also, avoid routing sensitive signals near the inductor.
  • The recommended inductor value is 1.5uH to 3.3uH, and a shielded inductor with a low DCR (e.g., 0.5 ohms or less) is recommended for optimal performance.
  • 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.
  • The MP9943GQ-Z can deliver up to 3A of output current, but it's recommended to derate the output current based on the input voltage, output voltage, and ambient temperature.
