LTC3639MPMSE#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the VIN pin is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
  • To minimize EMI, it's recommended to keep the input and output capacitors close to the IC, use a solid ground plane, and keep the high-frequency switching nodes (e.g., LX) away from sensitive analog nodes. Additionally, use a shielded inductor and orient it to minimize radiation.
  • A low-ESR ceramic capacitor (e.g., X5R or X7R) with a value between 10uF to 22uF is recommended for the output capacitor. The exact value depends on the specific application requirements and output voltage ripple tolerance.
  • The switching frequency of the LTC3639MPMSE#PBF can be adjusted by connecting a resistor (RFREQ) between the FREQ pin and GND. The frequency can be calculated using the formula provided in the datasheet.
  • The maximum output current that the LTC3639MPMSE#PBF can deliver is 3A, but it's recommended to derate the output current based on the ambient temperature and other application-specific factors.
