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%. These converters are designed and manufactured in a facility qualified to ISO9001 and certified to MIL- PRF-38534 and MIL-STD-883. This product may incorporate one or more of the following U.S. patents: 5,784,266 5,790,389 5,963,438 5,999,433 6,005,780 6,084,792 6,118,673 FEATURES • High Reliability • 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 • Industry Standard Pinout • Input Transient Voltage: 50 Volts for 1 second • Radiation Hardened Version Available • Precision Seam Welded Hermetic Package • High Power Density: > 80 W/in3 • Custom Versions Available • Additional Environmental Screening Available • Meets MIL-STD-461C and MIL-STD-461D EMC Requirements When Used With a DVME28 EMI Filter • MIL-PRF-38534 Element Evaluated Components Figure 1 – DVFL2800S DC-DC Converter (Not To Scale) |
