RAC20-12SB Frequently Asked Questions (FAQs)

  • RECOM recommends a PCB layout with a large copper area for heat dissipation, and a minimum of 2oz copper thickness. A thermal via array under the module is also recommended.
  • Ensure that the input voltage is within the specified range, and that the input capacitor is sufficient to handle the inrush current. Also, ensure that the output capacitor is properly sized to handle the output voltage ripple.
  • The maximum allowed capacitance on the output is 220uF. Exceeding this value may cause instability or oscillation in the converter.
  • While the RAC20-12SB is rated for operation up to 80°C, it's recommended to derate the output power by 2.5% per degree above 60°C to ensure reliable operation.
  • RECOM recommends using a TVS diode or a transient voltage suppressor at the input to protect the converter from voltage transients and spikes.
