L6599ATDTR datasheet by STMicroelectronics

L6599ATDTR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the L6599ATDTR can handle?
  The L6599ATDTR can handle input voltages up to 60V, but it's recommended to keep it below 50V for reliable operation.
• How do I ensure the L6599ATDTR operates within the recommended temperature range?
  The L6599ATDTR operates within the recommended temperature range of -40°C to 150°C. Ensure good thermal design, use a heat sink if necessary, and avoid overheating the device.
• What is the purpose of the bootstrap capacitor (CBOOT) in the L6599ATDTR?
  The bootstrap capacitor (CBOOT) is used to generate the high-side gate drive voltage. It's essential for proper operation and should be chosen according to the datasheet recommendations.
• How do I calculate the output voltage of the L6599ATDTR?
  The output voltage of the L6599ATDTR is determined by the feedback resistors (RFB1 and RFB2) and the reference voltage (VREF). Use the formula: VOUT = VREF x (1 + RFB2/RFB1).
• What is the maximum switching frequency of the L6599ATDTR?
  The maximum switching frequency of the L6599ATDTR is 500 kHz. However, it's recommended to operate at a lower frequency (e.g., 300 kHz) for better efficiency and reduced EMI.
