LTM8047EY#PBF Frequently Asked Questions (FAQs)

  • A 2-layer or 4-layer PCB with a solid ground plane and thermal vias under the IC is recommended. This helps to dissipate heat efficiently and reduce thermal resistance.
  • Use a soft-start circuit to limit the inrush current during start-up, and ensure that the input voltage rises slowly (e.g., using a ramp-up circuit). For shutdown, use a soft-shutdown circuit to gradually reduce the output voltage.
  • Use a low-ESR ceramic capacitor (e.g., X5R or X7R) with a value of 10-22uF, depending on the input voltage and output current requirements.
  • Use a shielded inductor, keep the switching node (SW) away from sensitive nodes, and use a common-mode choke or EMI filter to reduce radiated emissions.
  • The maximum allowed output capacitance depends on the output voltage and current. As a general rule, keep the output capacitance below 100uF to ensure stable operation.
