DVTR2800S Series HIGH RELIABILITY HYBRID DC-DC CONVERTERS DESCRIPTION FEATURES The DVTR 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 DVTR series is a magnetic feedback circuit that is radiation immune. Operating at a nominal fixed frequency of 475 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 40 Watts Output Power Output Voltage Trim Up +10% 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 Seam Seal or Solder Seal Hermetic Package High Power Density: > 40 W/in3 Custom Versions Available Additional Environmental Screening Available Meets MIL-STD-461C and MIL-STD-461D EMC Requirements When Used With a DVMC28 EMI Filter Flanged and Non-flanged Versions Available.
