RPMGS12-20 - RECOM Power

RPMGS12-20 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 2 oz copper thickness is recommended. Additionally, it's essential to keep the PCB layout symmetrical to minimize thermal gradients.
• Can I use this module in a high-vibration environment?
  Yes, the RPMGS12-20 is designed to withstand vibrations up to 10G peak acceleration, making it suitable for use in industrial and transportation applications. However, it's essential to ensure proper mounting and screw torque to prevent damage.
• How do I ensure reliable start-up in a low-input voltage condition?
  To ensure reliable start-up in a low-input voltage condition, RECOM recommends using a soft-start circuit or a voltage supervisor to delay the module's start-up until the input voltage reaches a minimum of 10V. This prevents the module from drawing excessive current during start-up.
• What is the maximum allowed capacitance on the output?
  The maximum allowed capacitance on the output is 220uF. Exceeding this value may cause instability or oscillation in the output voltage. It's essential to follow the recommended output capacitance value to ensure stable operation.
• Can I use this module in a high-altitude application?
  Yes, the RPMGS12-20 is designed to operate up to 5000 meters above sea level. However, it's essential to consider the derating of the module's power rating at high altitudes due to the lower air pressure and oxygen levels.
