DVHF2800S 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 is a magnetic feedback circuit that is radiation immune. Operating at a nominal fixed frequency of 450 kHz, these regulated, isolated units utilize well controlled undervoltage lockout circuitry to eliminate slow start-up problems. · · · These converters are designed and manufactured in a facility qualified to ISO9001, compliant to AS9000, and certified to MIL-PRF-38534 and MIL-STD-883. · · · · · · · · · · · · · · High Reliability Very Low Output Noise Wide Input Voltage Range: 15 to 50 Volts per MIL-STD-704 Up to 20 Watts Output Power Radiation Immune Magnetic Feedback Circuit NO Use of Optoisolators Undervoltage Lockout Industry Standard Pinout High Input Transient Voltage: 80 Volts for 1 sec per MIL-STD-704A Radiation Hardened Version Available Precision Projection Welded Hermetic Package High Power Density: > 37 W/in3 Custom Versions Available Additional Environmental Screening Available Meets MIL-STD-461C and MIL-STD-461D EMC Requirements When Used With a DVMH28 EMI Filter Flanged and Non-flanged Versions Available.
