JCK1524D15 datasheet by XP Power

JCK1524D15 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 is also recommended.
• 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 of the input voltage to prevent inrush currents. Additionally, a minimum input capacitance of 10uF is recommended.
• What is the maximum allowed capacitance on the output?
  The maximum allowed capacitance on the output is 220uF. Exceeding this value may affect the stability of the converter.
• Can I use the JCK1524D15 in a redundant configuration?
  Yes, the JCK1524D15 can be used in a redundant configuration. However, XP Power recommends using a diode orifice or a redundancy module to ensure proper operation and to prevent back-feeding of power.
• What is the recommended input fuse rating?
  The recommended input fuse rating is 2A slow-blow. This ensures that the fuse does not trip during normal operation, but still provides protection against fault conditions.
