DVWR2800T DC-DC Converter

VPT’s DVWR Series incorporates a dual topology with independent control loops to ensure excellent regulation, especially for a low voltage output.

Features:

  • Up to 25W of output power
  • Triple outputs of 3.3V/ ±12V and 3.3V/ ±15V
  • Separate control loops for 3.3V main and auxiliaries, for minimal cross regulation
  • Full performance over-55° C to +125° C military temperature range
  • Wide input voltage range: 15 to 50 volts with 80V transient
  • Fault tolerant magnetic feedback circuit
  • Very low output noise
  • Host of circuit protection features
  • Extremely low profile (.415 inches) and light weight (54/58g) fully hermetic package
  • Fixed switching frequency
  • Ensure excellent thermal performance and unit isolation by using with the thermal pad TP-004

Compliances and Certifications:

  • Available qualified to MIL-PRF-38534 Class H, DLA SMD #5962-16203
  • VPT’s in house legacy Class KL1 available
  • Manufactured in an MIL-PRF-38534 Class H and Class K, and ISO9001 certified manufacturing facility
  • MIL-STD-704A input voltage requirements
  • DO-160
  • MIL-STD-883 military and space environmental screening available
  • MIL-STD-461 C-G when used with a VPT DVMC28 EMI filter
