VPP16-620 - Triad Magnetics

VPP16-620 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Triad Magnetics recommends a symmetrical PCB layout with the transformer centered on the board, and the primary and secondary windings on opposite sides of the board to minimize electromagnetic interference (EMI).
• How do I ensure reliable operation at high temperatures?
  To ensure reliable operation at high temperatures, Triad Magnetics recommends derating the transformer's power rating by 1% for every 1°C above 40°C, and using a thermal interface material (TIM) to improve heat transfer between the transformer and the heat sink.
• What is the maximum allowable voltage imbalance between the primary and secondary windings?
  Triad Magnetics recommends that the voltage imbalance between the primary and secondary windings should not exceed 10% to prevent overheating and ensure reliable operation.
• Can I use the VPP16-620 in a parallel configuration to increase power rating?
  Yes, the VPP16-620 can be used in a parallel configuration to increase the power rating, but Triad Magnetics recommends that the transformers be matched in terms of inductance, resistance, and turns ratio to ensure proper operation and to prevent uneven current sharing.
• What is the recommended creepage distance between the primary and secondary windings?
  Triad Magnetics recommends a minimum creepage distance of 4 mm between the primary and secondary windings to ensure electrical isolation and to prevent arcing or tracking.
