RS3-123.3S Frequently Asked Questions (FAQs)

  • RECOM recommends a PCB layout with a large copper area for heat dissipation, and a minimum of 2 oz copper thickness. A thermal via array under the module is also recommended.
  • Ensure the input voltage is within the specified range, and the input capacitance is sufficient to handle the inrush current. Also, add a soft-start circuit or a ramp-up circuit to the enable pin to prevent high inrush currents.
  • The maximum allowed capacitance on the output is 220uF. Exceeding this value may cause instability or oscillations in the converter.
  • The RS3-123.3S is rated for operation up to 80°C ambient temperature. For higher temperatures, derating of the output power is required. Consult the datasheet for derating curves.
  • Use a TVS diode or a transient voltage suppressor at the input to protect the converter from voltage spikes and transients.
