LT3573IMSE#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that the LT3573 can handle is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
  • To optimize the layout for the LT3573, keep the input and output capacitors close to the IC, use a solid ground plane, and minimize the length of the traces between the IC and the capacitors. Also, keep the switching node (SW pin) away from sensitive nodes.
  • The recommended operating frequency for the LT3573 is between 200 kHz to 2 MHz. However, the optimal frequency depends on the specific application and the desired trade-off between efficiency and noise.
  • To select the right inductor for the LT3573, consider the inductor's saturation current, DC resistance, and core material. A good starting point is to choose an inductor with a saturation current rating of at least 1.5 times the peak current, and a DC resistance of less than 100 mΩ.
  • The maximum output current that the LT3573 can deliver is 3A, but it's recommended to derate the output current based on the ambient temperature and the desired reliability.
