LTM4691EV#PBF Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the thermal pad connected to the ground plane to improve heat dissipation.
  • Use a soft-start circuit to limit the inrush current during start-up. For shutdown, ensure a controlled ramp-down of the output voltage to prevent voltage spikes.
  • 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 add a common-mode choke to reduce EMI emissions.
  • The output voltage deviation should be within ±10% of the nominal output voltage to ensure reliable operation and prevent damage to the device.
