L6591 Frequently Asked Questions (FAQs)

  • The maximum switching frequency of L6591 is 500 kHz, but it can be operated up to 1 MHz with some limitations.
  • Choose a transformer with a turns ratio that matches the input and output voltage requirements, and ensure it can handle the maximum power and frequency of your design.
  • The bootstrap capacitor (Cboot) is used to generate the high-side gate drive voltage for the power MOSFET, allowing the IC to drive the MOSFET's gate above the input voltage.
  • The output voltage is set by the feedback voltage divider (R1 and R2) and the internal reference voltage (2.5V). The output voltage is calculated as Vout = 2.5V x (1 + R2/R1).
  • The maximum input voltage for L6591 is 30V, but it can be operated up to 40V with some limitations and proper design considerations.
