RAC04-05SGB - RECOM Power

RAC04-05SGB Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  RECOM 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 100°C.
• How do I ensure the converter's reliability and long-term stability in high-temperature environments?
  To ensure reliability and stability, RECOM recommends following the derating curves, using a suitable heat sink, and ensuring good airflow around the converter. Additionally, consider using a conformal coating to protect the device from moisture and contamination.
• What is the maximum capacitance I can use on the output of the RAC04-05SGB?
  RECOM recommends using a maximum output capacitance of 220uF to ensure stability and prevent oscillations. Exceeding this value may lead to instability or even damage to the converter.
• Can I use the RAC04-05SGB in a redundant or parallel configuration?
  Yes, the RAC04-05SGB can be used in a redundant or parallel configuration, but RECOM recommends consulting their application notes and following specific guidelines to ensure proper operation and synchronization.
• What is the typical efficiency of the RAC04-05SGB, and how does it vary with load and temperature?
  The typical efficiency of the RAC04-05SGB is around 85-90% at full load, depending on the input voltage and temperature. Efficiency may decrease at lower loads or higher temperatures. Consult RECOM's efficiency curves and application notes for more information.
