LM250K Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LM25065 is 42V, but it's recommended to keep it below 40V 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 recommended in the datasheet or to use an inductor selection tool provided by STMicroelectronics or other online resources.

  • The bootstrap capacitor (CBOOT) is used to generate the gate drive voltage for the high-side MOSFET. The recommended value is 10nF to 22nF, but it may need to be adjusted based on the specific application and layout.

  • To ensure stability, follow the layout guidelines in the datasheet, use a low-ESR output capacitor, and add a small ceramic capacitor (e.g., 10nF) between the VOUT and GND pins. Additionally, make sure the input voltage is within the recommended range and the output voltage is set correctly.

  • The maximum output current of the LM25065 is 2.5A, but it's recommended to derate the output current based on the ambient temperature and the input voltage to ensure reliable operation.
