VQA-S15-D15-SIP Frequently Asked Questions (FAQs)

  • CUI recommends a 2-layer PCB with a solid ground plane and thermal vias to dissipate heat. A minimum of 1 oz copper thickness is recommended. For thermal management, a heat sink or thermal interface material can be used to reduce thermal resistance.
  • The VQA-S15-D15-SIP has built-in input voltage transient protection up to 100V for 100ms. However, for prolonged transients or spikes, external protection devices such as TVS diodes or varistors may be necessary.
  • The VQA-S15-D15-SIP can drive up to 10uF of capacitance load. Exceeding this limit may affect the converter's stability and performance.
  • Yes, the VQA-S15-D15-SIP can be used in a redundant or N+1 configuration to achieve high availability and redundancy. However, additional external circuitry and control logic may be required.
  • The typical efficiency of the VQA-S15-D15-SIP is around 85% at 50% load, 80% at 25% load, and 75% at 10% load. Efficiency may vary depending on input voltage, output voltage, and operating temperature.
