LTM4646IY Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias connecting the top layer to the bottom layer is recommended. This helps to dissipate heat efficiently and reduces thermal resistance.
  • Use the provided filter design tool or consult the application note AN136 to determine the optimal output filter component values. A good starting point is to use a 2nd order LC filter with a 1uH inductor and a 10uF capacitor.
  • The maximum allowed input voltage transient is 20% above the maximum recommended input voltage, which is 5.5V. This means the device can withstand up to 6.6V input voltage for a short duration.
  • Use a soft-start circuit to limit the inrush current during start-up. For shutdown, use a controlled shutdown sequence to prevent voltage spikes and ensure a clean shutdown.
  • A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended. This helps to filter out input noise and reduce the risk of oscillations.
