LTM4693IV#PBF Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the thermal pads away from high-current paths and ensure good airflow around the device.
  • Use the datasheet's recommended output filter components and layout guidelines. Ensure the output capacitors have low ESR and are placed close to the output pins. Add a small ceramic capacitor in parallel with the main output capacitor to reduce high-frequency noise.
  • The device can withstand input voltage transients up to 20% above the maximum recommended input voltage (Vin) for a duration of 100ms. However, it's recommended to use input voltage transient protection circuits to ensure reliable operation.
  • Use a soft-start circuit to limit the inrush current during start-up. Ensure the input voltage rises slowly (typically 10ms to 100ms) to prevent excessive inrush current. For shutdown, use a controlled shutdown sequence to prevent voltage spikes and ensure a clean shutdown.
  • A thermal interface material with a thermal conductivity of at least 1 W/m-K is recommended. Examples include thermal tapes, thermal greases, or thermal pads with a thermal conductivity of 1 W/m-K or higher.
