DVFL2800D Series HIGH RELIABILITY HYBRID DC-DC CONVERTERS DESCRIPTION FEATURES 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 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 500 kHz, these regulated, isolated units utilize a high speed magnetic feedback design and well controlled undervoltage lockout circuitry to eliminate slow startup 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 MILPRF-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 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 Fault Tolerant 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 Precision Seam Welded Hermetic Package High Power Density: > 80 W/in3 Custom Versions Available Additional Environmental Screening Available Meets MIL-STD-461 Revisions C, D, E and F EMC Requirements When Used With VPT's EMI Filters MIL-PRF-38534 Element Evaluated Components Space Applications should consider VPT's "S" Series of Radiation Tolerant Power Conversion Devices.
