L6566B Frequently Asked Questions (FAQs)

  • The L6566B can handle input voltages up to 30V, but it's recommended to keep it below 25V 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 or consult with an application note.
  • The bootstrap capacitor (CBOOT) is used to generate the high-side gate drive voltage. Choose a capacitor with a value between 10nF to 100nF, depending on the switching frequency and output current.
  • To ensure stability, make sure to follow the layout guidelines, use a low-ESR output capacitor, and add a small ceramic capacitor (e.g., 10nF) between the VCC and GND pins.
  • Yes, the L6566B can be used in a synchronous rectification configuration, but it requires additional external components and careful design consideration to ensure proper operation.
