| DESCRIPTION The DVWR series of high reliability DC-DC converters is operable over the full military to +125 �C) temperature range with no power derating. Unique to the DVWR series is a fault tolerant magnetic feedback circuit. Operating at a nominal fixed frequency of 325 kHz per stage, these regulated, isolated units utilize 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 MILPRF-38534 and MIL-STD-883. This product may incorporate one or more of the following U.S. patents: FEATURESHigh Reliability Very Low Output Noise Wide Input Voltage Range: to 50 Volts per to 25 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 Seam Welded or Solder Seal Hermetic Package High Power Density: 28 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.
