LM3524DN Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM3524DN is 40V, but it's recommended to keep it below 35V for reliable operation.
  • To ensure the LM3524DN operates within its SOA, make sure to keep the input voltage, output current, and junction temperature within the recommended limits. Also, ensure proper heat sinking and thermal management.
  • The bootstrap capacitor (CBOOT) is used to generate the high-side gate drive voltage for the internal power MOSFET. It's essential for proper operation and should be selected based on the input voltage and switching frequency.
  • Yes, the LM3524DN can be used in a synchronous rectification configuration, but it requires an external Schottky diode or a synchronous rectifier controller to control the low-side MOSFET.
  • The minimum input capacitance required for the LM3524DN can be calculated based on the input voltage, output current, and switching frequency. A general rule of thumb is to use a capacitance value of at least 10uF per ampere of output current.
