DVHV2800S Series HIGH RELIABILITY HYBRID DC-DC CONVERTERS DESCRIPTION FEATURES The DVHV 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 DVHV 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. 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 Very Low Output Noise Output Voltage Trim Up +10% or Down –20% Wide Input Voltage Range: 15 to 50 Volts per MIL-STD-704 Up to 15 Watts Output Power Radiation Immune 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 Radiation Hardened Version Available Precision Seam Seal or Solder Seal Hermetic Package 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.
