L4984D Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the L4984D is 28V, but it's recommended to keep it below 24V for reliable operation.
  • The inductor value depends on the output current, switching frequency, and input voltage. A good starting point is to use the inductor value recommended in the datasheet (e.g., 10uH for the L4984D). You can also use online inductor selection tools or consult with an experienced engineer.
  • The bootstrap capacitor (CBOOT) is used to generate the high-side gate drive voltage. Choose a capacitor with a value between 10nF to 100nF, and a voltage rating that exceeds the maximum input voltage. A 22nF capacitor is a good starting point.
  • Ensure good thermal design by providing adequate heat sinking, using a thermally conductive PCB material, and keeping the component away from heat sources. Monitor the junction temperature (TJ) and adjust the design as needed to keep TJ below 150°C.
  • The minimum ESR required for the output capacitor depends on the output current and ripple requirements. A good starting point is to use an output capacitor with an ESR of 0.1 ohms or less.
