DVHF2800D Series HIGH RELIABILITY HYBRID DC-DC CONVERTERS DESCRIPTION FEATURES 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 startup problems. 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 High Reliability Very Low Output Noise 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 Additional Environmental Screening Available Meets MIL-STD-461 Revisions C, D, E and F EMC Requirements When Used With VPT's EMI Filters Flanged and Non-flanged Versions Available. MIL-PRF-38534 Element Evaluated Components Space Applications should consider VPT's "S" Series of Radiation Tolerant Power Conversion Devices. Contact VPT for details.
