RI3-2409S - RECOM Power

RI3-2409S Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  RECOM Power Inc recommends a PCB layout with a large copper area for heat dissipation, and a thermal management system with a heat sink and thermal interface material to keep the junction temperature below 125°C.
• How do I ensure reliable start-up and shutdown of the converter?
  To ensure reliable start-up and shutdown, RECOM recommends a soft-start circuit to limit the inrush current, and a shutdown circuit to discharge the output capacitors. Additionally, a voltage supervisor can be used to monitor the input voltage and prevent start-up during brownout conditions.
• What is the maximum allowed capacitance on the output?
  The maximum allowed capacitance on the output of the RI3-2409S is 2200uF. Exceeding this value may cause instability or oscillation in the converter.
• Can I use the RI3-2409S in a redundant or parallel configuration?
  Yes, the RI3-2409S can be used in a redundant or parallel configuration, but RECOM recommends using a dedicated ORing diode or a redundancy module to ensure reliable operation and prevent back-feeding of power.
• What is the recommended input fuse rating and type?
  RECOM recommends using a fuse with a rating of 5A to 10A, depending on the input voltage and current requirements. A slow-blow fuse type is recommended to handle the inrush current during start-up.
