Description

The DVGF+ Series triple output DC-DC converter is the first converter in its class to provide a 3.3V main output to satisfy low voltage requirements on newer aircraft, weapon, and other military and avionics system platforms. Manufactured in VPT’s facility qualified to MILPRF-38534 and MIL-STD-883, the DVGF+ will function in the most rugged of application environments.

Features

  • Up to 12.5W output power
  • Triple outputs of 3.3V/±12V and 3.3V/±15V
  • Very low output noise
  • 15 to 50 volts per MIL-STD-704, an essential input range for military applications
  • Full performance over -55°C to +125°C military temperature range
  • Fault tolerant magnetic feedback circuit
  • No optoisolators, greatly enhancing reliability
  • A host of circuit protection features
  • Low profile (.355″) and light weight (26/29g) hermetic package
