LM5036RJBR Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the IC, and use short, wide traces for the high-current paths.
  • Use a soft-start circuit to limit the inrush current during start-up, and ensure the input voltage rises slowly (e.g., using a ramp-up circuit). For shutdown, use a soft-shutdown circuit to gradually reduce the output voltage.
  • The maximum allowed input voltage ripple is 10% of the nominal input voltage. Exceeding this may affect the converter's stability and efficiency.
  • Yes, the LM5036RJBR can be used in a synchronous rectification configuration, which can improve efficiency. However, this requires additional components and careful design to ensure proper operation.
  • Use a combination of capacitors and inductors to filter the output voltage. The output filter should be designed to attenuate the switching frequency and its harmonics, ensuring the output voltage ripple is within the desired specifications.
