LT3591EDDB#TRMPBF Frequently Asked Questions (FAQs)

  • A 2-layer or 4-layer PCB with a solid ground plane and thermal vias under the IC is recommended. This helps to dissipate heat efficiently and reduce thermal resistance.
  • Ensure that the input voltage rises monotonically during start-up, and the output voltage is properly sequenced during shutdown. Also, add a soft-start capacitor to limit the inrush current.
  • The maximum allowed capacitance is dependent on the output voltage and current. As a general rule, keep the output capacitance below 100uF to avoid stability issues.
  • Use a shielded inductor, keep the switching node (SW) away from sensitive nodes, and add a common-mode choke to reduce EMI. Also, ensure good PCB layout practices, such as keeping the power stage away from sensitive analog circuits.
  • Use a low-ESR ceramic capacitor (e.g., X5R or X7R) with a value between 10uF to 22uF, depending on the input voltage and current requirements.
