DVHE2800S DC-DC Converter

The DVHE Series of DC-DC converters can be used alone or in conjunction with the DVPL point of load converters to create an efficient distributed power system.  The DVHE packs 50W in a standard hermetic case at more than 90% efficiency. This is 66% more current than previous generations offered in this existing standard case size.

Save board size, weight, heat and cost by using a single DVHE to power multiple point of load DC-DC converters instead of deploying multiple isolated DC-DC converters.

 

Features:

  • Single outputs of 1.9V, 2.5V, 3.3V, 5V
  • Extra-wide 16V to 40V input range with 50V transient
  • Extremely high efficiency – up to 90%
  • Up to 50W output power
  • Full operation over -55 °C to +125 °C military temperature range
  • Fault tolerant design with patented technology – no optoisolators
  • Very low input/output noise
  • Tiny size – 2.110″ x 1.125 x .427 and light weight (52 g max)
  • Host of circuit protection features
  • Fixed switching frequency
  • 500Vdc input/output isolation
  • Ensure excellent thermal performance and unit isolation by using with thermal pad TP-003

Compliances and Certifications:

  • Available qualified to MIL-PRF-38534 Class H and Class K: DLA SMD #5962-15230
  • MIL-PRF-38534 Class H and Class K certified manufacturing facility
  • MIL-STD-704A input voltage requirements
  • DO-160
  • ISO-9001
  • MIL-STD-883 military and space environmental screening available
  • MIL-STD-461 C-G when used with a VPT DVMC28 EMI filter
