CQB200-24S24 - Cincon

CQB200-24S24 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal design for optimal performance?
  Cincon recommends a 4-layer PCB with a dedicated ground plane and thermal vias to ensure efficient heat dissipation. A minimum of 2oz copper thickness is recommended for the top and bottom layers. Additionally, a thermal pad with a minimum size of 10mm x 10mm is recommended for the module's thermal interface.
• How do I ensure reliable start-up and shutdown of the converter?
  To ensure reliable start-up and shutdown, Cincon recommends a soft-start circuit with a minimum rise time of 10ms and a maximum inrush current of 10A. Additionally, a shutdown circuit with a minimum fall time of 10ms is recommended to prevent voltage overshoot.
• What is the maximum allowed capacitance on the output of the converter?
  Cincon recommends a maximum output capacitance of 220uF to prevent oscillation and ensure stability. Exceeding this value may lead to instability or even damage to the converter.
• How do I protect the converter from input voltage transients and surges?
  Cincon recommends using a TVS diode or a surge protector at the input of the converter to protect against voltage transients and surges. The TVS diode should be rated for the maximum expected input voltage and have a response time of less than 1ns.
• What is the recommended input fuse rating and type for the converter?
  Cincon recommends a fuse rating of 5A to 10A, depending on the application's current requirements. A slow-blow fuse (e.g., Littlefuse 5A or 10A) is recommended to prevent nuisance tripping during inrush current events.
