AC38S-Q datasheet by Comus International

AC38S-Q Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the AC38S-Q?
  Comus International recommends a 4-layer PCB with a solid ground plane, and to keep the input and output traces as short as possible to minimize EMI and noise.
• How do I ensure the AC38S-Q operates within its specified temperature range?
  Proper heat sinking and thermal management are crucial. Ensure good airflow, and consider using a heat sink or thermal interface material to keep the device within its operating temperature range of -40°C to +85°C.
• What is the maximum allowable voltage deviation for the AC38S-Q's input voltage?
  The AC38S-Q can tolerate up to ±10% deviation from its nominal input voltage without affecting its performance or reliability.
• Can I use the AC38S-Q in a redundant or parallel configuration for higher power output?
  Yes, the AC38S-Q can be used in redundant or parallel configurations, but it's essential to ensure proper synchronization and current sharing to avoid uneven stress and potential reliability issues.
• How do I troubleshoot common issues like output voltage instability or overheating in the AC38S-Q?
  Check the input voltage, output load, and ambient temperature. Verify proper PCB layout, heat sinking, and thermal management. Consult the datasheet and application notes for troubleshooting guidelines, and contact Comus International's technical support if necessary.
