DSW-424 - Stancor

DSW-424 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Stancor recommends a 4-layer PCB with a solid ground plane, and a separate layer for the power supply. Keep the input and output traces short and away from each other to minimize noise and EMI.
• How do I ensure reliable operation in high-temperature environments?
  Stancor recommends derating the output power by 1.5% per degree Celsius above 40°C. Ensure good airflow, and consider using a heat sink or thermal interface material to keep the device temperature below 125°C.
• What is the maximum allowed input voltage ripple?
  Stancor recommends keeping the input voltage ripple below 10% of the nominal input voltage to ensure stable operation and prevent damage to the device.
• Can I use the DSW-424 in a redundant or parallel configuration?
  Yes, the DSW-424 can be used in redundant or parallel configurations, but Stancor recommends using external ORing diodes and current sharing resistors to ensure proper operation and prevent damage.
• What is the typical start-up time for the DSW-424?
  The typical start-up time for the DSW-424 is around 10-15 ms, but this can vary depending on the input voltage, output load, and other factors.
