RSO-0505D - RECOM Power

RSO-0505D Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  RECOM recommends a PCB layout with a large copper area connected to the module's thermal pad to ensure good heat dissipation. A minimum of 1 oz copper thickness is recommended, and the copper area should be connected to a heat sink or a metal plate for further heat dissipation.
• How do I ensure the module's reliability in high-temperature environments?
  To ensure reliability in high-temperature environments, RECOM recommends following the derating curves provided in the datasheet. Additionally, the module should be mounted on a heat sink or a metal plate to dissipate heat, and the ambient temperature should be kept below 80°C.
• What is the recommended input capacitor value and type for this module?
  RECOM recommends using a low-ESR ceramic capacitor with a value of 10-22 μF and a voltage rating of 50-100 V. The capacitor should be placed as close as possible to the module's input pins to minimize noise and ripple.
• Can I use this module in a redundant or parallel configuration?
  Yes, the RSO-0505D can be used in a redundant or parallel configuration to achieve higher power or redundancy. However, RECOM recommends consulting with their application engineers to ensure proper design and implementation.
• What is the module's behavior during input voltage brownout or dropout?
  The RSO-0505D has a built-in undervoltage lockout (UVLO) feature that shuts down the module when the input voltage falls below 3.5 V. The module will automatically restart when the input voltage recovers to above 4.5 V.
