PDRB-60-24 - CUI Inc.

PDRB-60-24 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  CUI Inc recommends a PCB layout with a minimum of 2 oz copper thickness, 1 inch x 1 inch copper pad for heat sinking, and a thermal relief pattern around the device to ensure optimal thermal performance.
• How do I ensure reliable startup and shutdown of the PDRB-60-24?
  To ensure reliable startup and shutdown, CUI Inc recommends a soft-start circuit to limit inrush current, and a shutdown circuit that slowly discharges the output capacitor to prevent voltage spikes.
• What is the maximum allowable capacitance for the output filter capacitor?
  The maximum allowable capacitance for the output filter capacitor is 2200uF, as specified in the datasheet. Exceeding this value may cause instability or oscillation in the converter.
• Can I use the PDRB-60-24 in a high-temperature environment?
  While the PDRB-60-24 is rated for operation up to 85°C, CUI Inc recommends derating the output power by 2.5% per degree Celsius above 70°C to ensure reliable operation in high-temperature environments.
• How do I troubleshoot issues with the PDRB-60-24, such as output voltage instability or overheating?
  CUI Inc recommends checking the input voltage, output load, and PCB layout for any issues. Also, verify that the device is properly heatsinked and that the thermal relief pattern is correctly implemented. If issues persist, contact CUI Inc's technical support for further assistance.
