V48B28C250BL Frequently Asked Questions (FAQs)

  • Vicor recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to ensure optimal thermal performance.
  • To ensure reliable start-up, Vicor recommends a soft-start circuit to limit the inrush current and a hold-up capacitor to maintain output voltage during input voltage dips.
  • The maximum allowed capacitance on the output of the V48B28C250BL is 2200uF. Exceeding this value may cause instability or oscillation.
  • Yes, the V48B28C250BL can be used in a redundant configuration, but it requires careful consideration of the system design, including synchronization and ORing of the outputs.
  • Vicor recommends using an oscilloscope to monitor the input and output voltages, as well as the current sense pins, to troubleshoot issues with the V48B28C250BL.
