HIGH RELIABILITY HYBRID  
DC-DC CONVERTERS  
DESCRIPTION  
FEATURES  
High Reliability  
The DVFL 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 DVFL series is a magnetic feedback circuit  
that is radiation immune. Operating at a nominal  
fixed frequency of 500 kHz, these regulated, isolated  
units utilize well-controlled undervoltage lockout  
circuitry to eliminate slow start-up problems. The  
current sharing function allows a maximum of five  
units to be connected in parallel to boost the total  
output power to 5 times. The output voltage is  
trimmable up to +10% or down –20%.  
Parallel Up to 5 Units With Current Sharing  
Output Voltage Trim Up +10% or Down –20%  
Wide Input Voltage Range: 16 to 40 Volts per  
MIL-STD-704  
Up to 120 Watts Output Power  
Radiation Immune Magnetic Feedback Circuit  
NO Use of Optoisolators  
Undervoltage Lockout  
Indefinite Short Circuit Protection  
Current Limit Protection
