L4960 Frequently Asked Questions (FAQs)

  • The L4960 can handle input voltages up to 40V, but it's recommended to keep it below 36V for optimal performance and reliability.
  • 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 EN (Enable) pin is used to enable or disable the regulator. When EN is high, the regulator is enabled, and when EN is low, the regulator is disabled. This pin can be used to implement power sequencing or to shut down the regulator when not in use.
  • To ensure stability, follow the layout guidelines in the datasheet, use a suitable output capacitor, and ensure that the input capacitor is properly sized. Additionally, avoid using long traces and minimize the distance between the regulator and the output capacitor.
  • The L4960 can deliver up to 3A of output current, but this depends on the input voltage, output voltage, and ambient temperature. Be sure to check the datasheet for the specific current rating at your operating conditions.
