L6598D Frequently Asked Questions (FAQs)

  • The L6598D can handle input voltages up to 60V, but it's recommended to keep it below 50V for reliable operation.
  • Choose a transformer with a turns ratio that matches the output voltage requirement. Ensure the transformer's primary inductance is within the recommended range (10-100 μH) and the magnetizing inductance is above 10 μH.
  • The bootstrap capacitor (CBOOT) is used to generate the high-side gate drive voltage for the power MOSFET. It's essential for proper operation and should be chosen according to the datasheet recommendations (e.g., 10-22 nF).
  • The output voltage is set by the feedback resistors (RFB1 and RFB2) and the internal reference voltage (2.5V). Use the formula: Vout = 2.5V x (1 + RFB2/RFB1) to calculate the output voltage.
  • The maximum switching frequency of the L6598D is 500 kHz, but it's recommended to operate at a lower frequency (e.g., 300-400 kHz) for better efficiency and reduced EMI.
