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 is a fault tolerant
magnetic feedback circuit. Operating at a nominal
fixed frequency of 325 kHz per stage, these
regulated, isolated units utilize 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 15 Watts Output Power
Fault Tolerant Magnetic Feedback Circuit
NO Use of Optoisolators
Undervoltage Lockout
Indefinite Short Circuit Protection
Current Limit Protection

•
These converters are designed and manufactured in
a facility qualified to ISO9001 and certified to MIL-
PRF-38534 and MIL-STD-883.
Industry Standard Pinout
High Input Transient Voltage: 80 Volts for 1 sec
per MIL-STD-704A
