DVFL2800S DC-DC Converter

With no stacked capacitors, this converter is ready for rugged assignments. VPT’s DVFL packs over 80W/in3 in a small, 100% hermetic package while offering a significant price advantage over similar competitive products.

Features:

  • Single outputs of 3.3V, 5V, 6.3V, 7V, 8V, 9.5V, 12V, 15V, 18V, and 28V
  • Wide 16V to 40V input range with 50V transient
  • Up to 120W output power
  • Full operation over -55°C to +125°C military temperature range
  • Parallel operation with current sharing up to five units
  • Fault tolerant design with patented technology – no optocouplers
  • Fixed switching frequency
  • Extremely low profile (.400 inches) and light weight (86g) fully hermetic packaging
  • 500Vdc input/output isolation
  • Ensure excellent thermal performance and unit isolation by using with the thermal pad TP-001
