JCA0624D02 - XP POWER

JCA0624D02 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  XP Power 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 can also improve heat dissipation.
• How do I ensure reliable start-up of the converter in my application?
  To ensure reliable start-up, XP Power recommends a soft-start circuit or a ramp-up voltage supply to prevent inrush currents. Additionally, a minimum input voltage of 10V is recommended for reliable start-up.
• What is the maximum allowable capacitance on the output of the converter?
  The maximum allowable capacitance on the output of the JCA0624D02 is 2200uF. Exceeding this value may cause instability or oscillations in the converter.
• Can I use the JCA0624D02 in a high-temperature environment?
  While the JCA0624D02 is rated for operation up to 80°C, XP Power recommends derating the output power by 2.5% per degree above 60°C to ensure reliable operation in high-temperature environments.
• How do I troubleshoot issues with the converter's output voltage regulation?
  To troubleshoot output voltage regulation issues, check the input voltage, output load, and PCB layout for any anomalies. Verify that the output voltage sense lines are properly connected and not subject to noise or interference.
