DVGF+2800T DC-DC Converter
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
- Fixed switching frequency
