RACD04-700 - RECOM Power

RACD04-700 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 operation with a high-capacitance output filter?
  To ensure reliable start-up and operation, RECOM recommends using a soft-start circuit or a ramp-up circuit to limit the inrush current, and selecting output capacitors with a low ESR and high ripple current rating.
• What is the maximum allowed voltage deviation on the input pins?
  The maximum allowed voltage deviation on the input pins is ±10% of the nominal input voltage, and the device can tolerate short-term transients up to 20% without damage.
• How do I implement overvoltage protection (OVP) and undervoltage protection (UVP) for the output voltage?
  RECOM recommends using external OVP and UVP circuits, such as a voltage supervisor IC or a discrete component circuit, to monitor the output voltage and shut down the converter in case of a fault.
• What is the recommended fuse rating and type for overcurrent protection?
  The recommended fuse rating is 5A to 10A, depending on the application, and a slow-blow fuse type is recommended to allow for temporary overcurrent conditions.
