L6986 Frequently Asked Questions (FAQs)

  • The L6986 can handle a maximum input voltage of 38V, but it's recommended to keep it below 36V 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 provided in the datasheet, and then fine-tune the value based on the specific application requirements.
  • The EN (enable) pin is used to turn the regulator on or off. 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 turn off the regulator when not in use.
  • To ensure stability, make sure to follow the PCB layout guidelines, use a suitable output capacitor, and add a compensation network (Rc and Cc) as recommended in the datasheet. Additionally, ensure that the input and output capacitors are placed close to the IC and that the layout is symmetrical.
  • The L6986 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.
