L6565DTR Frequently Asked Questions (FAQs)

  • The L6565DTR 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 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 L6565DTR can deliver up to 5A of output current, but it's recommended to derate the output current based on the ambient temperature and the thermal design of the application.
