DVHF2800S Series

HIGH RELIABILITY HYBRID

DC-DC CONVERTERS

DESCRIPTION

FEATURES

•

High Reliability

Very Low Output Noise

The DVHF series of high reliability DC-DC converters

is operable over the full military (-55 °C to +125 °C)

temperature range with no power derating. Unique

to the DVHF series are robust and effective input and

output filters which provide dramatically reduced

input and output noise performance when compared

to other manufacturers competing devices.

Operating at a nominal fixed frequency of 450 kHz,

these regulated, isolated units utilize a high speed

magnetic feedback design and well controlled

undervoltage lockout circuitry to eliminate slow start-

up problems.

Wide Input Voltage Range: 15 to 50 Volts per

MIL-STD-704

Up to 20 Watts Output Power

Fault Tolerant Magnetic Feedback Circuit

NO Use of Optoisolators

•

Undervoltage Lockout

Indefinite Short Circuit Protection

Current Limit Protection

Industry Standard Pinout

High Input Transient Voltage: 80 Volts for 1 sec

per MIL-STD-704A

Precision Projection Welded Hermetic Package

High Power Density: > 37 W/in³

Custom Versions Available

These converters are designed and manufactured in

a facility qualified to ISO9001 and certified to MIL-

PRF-38534 and MIL-STD-883.

•

Additional Environmental Screening Available

Meets MIL-STD-461 Revisions C, D, E and F

EMC Requirements When Used With VPT’s
