L6569A Frequently Asked Questions (FAQs)

  • The L6569A can handle input voltages up to 40V, but it's recommended to keep it below 35V for reliable operation.
  • The inductor value depends on the output voltage, output current, and switching frequency. A good starting point is to use the inductor selection guide in the datasheet, and then fine-tune the value based on your specific application requirements.
  • The bootstrap capacitor (CBOOT) is used to generate the high-side gate drive voltage. The recommended value is 10nF to 22nF, but it may need to be adjusted based on the specific application requirements and the value of the high-side MOSFET.
  • To ensure CCM operation, the inductor value should be chosen such that the inductor current ripple is less than 30% of the output current. Additionally, the output capacitor value should be sufficient to filter out the ripple voltage.
  • The L6569A can deliver up to 5A of output current, but this depends on the input voltage, output voltage, and thermal considerations. It's recommended to check the thermal derating curves in the datasheet to ensure reliable operation.
