LTM4643EY#PBF Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. The device's thermal pad should be connected to the ground plane using multiple thermal vias.
  • Ensure that the input voltage rises monotonically during start-up and falls monotonically during shutdown. A soft-start circuit can be used to control the input voltage ramp rate.
  • The maximum capacitive load is not explicitly stated in the datasheet, but as a general rule, the device can drive up to 10nF of capacitance. However, this may vary depending on the specific application and layout.
  • Use a shielded enclosure, keep the device and its associated components away from antennas and other EMI-sensitive components, and use a common-mode choke or ferrite bead to filter the input voltage.
  • A simple RC filter with a 1uF capacitor and a 10Ω resistor is recommended to filter the input voltage and reduce noise.
