L6566ATR Frequently Asked Questions (FAQs)

  • The L6566ATR can handle a maximum input voltage of 30V, but it's recommended to keep it below 28V 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 value calculation formula provided in the datasheet, and then adjust based on the 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 stability, make sure to follow the layout guidelines in the datasheet, use a low-ESR output capacitor, and add a small ceramic capacitor (e.g., 10nF) between the VCC pin and GND. Additionally, adjust the compensation components (R1, R2, C1, and C2) according to the application requirements.
  • The L6566ATR can deliver up to 3A of output current, but the actual current limit depends on the input voltage, output voltage, and thermal conditions. Make sure to check the thermal derating curves in the datasheet to ensure reliable operation.
