| DESCRIPTION The DVFL 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 DVFL series is a magnetic feedback circuit that is radiation immune. Operating at a nominal fixed frequency of 500 kHz, these regulated, isolated units utilize well-controlled undervoltage lockout circuitry to eliminate slow start-up problems. The current sharing function allows a maximum of five units to be connected in parallel to boost the total output power to 5 times. The output voltage is trimmable +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: FEATURESHigh Reliability Parallel to 5 Units With Current Sharing Output Voltage Trim +10% or Down �20% Wide Input Voltage Range: to 40 Volts per to 120 Watts Output Power Radiation Immune Magnetic Feedback Circuit NO Use of Optoisolators Undervoltage Lockout Indefinite Short Circuit Protection Current Limit Protection Industry Standard Pinout Input Transient Voltage: 50 Volts for 1 second Radiation Hardened Version Available Precision Seam Welded Hermetic Package High Power Density: 80 W/in3 Custom Versions Available Additional Environmental Screening Available Meets MIL-STD-461C and MIL-STD-461D EMC Requirements When Used With a DVME28 EMI Filter MIL-PRF-38534 Element Evaluated Components 11314 4th Avenue West, Suite 206 Everett, WA 98204 http://www.vpt-inc.com Sales Information: Phone: (425) 353-3010 Fax: (425) 353-4030 E-mail: vptsales@vpt-inc.com SPECIFICATIONS (TCASE to +125�C, VIN � 5%, Full Load, Unless Otherwise Specified)Input Voltage (Continuous) Input Voltage (Transient, 1 second) Output Power1 Power Dissipation (Full Load, TCASE +125�C) 40 VDC 50 Volts 120 Watts 41 Watts Junction Temperature Rise to Case Storage Temperature Lead Solder Temperature (10 seconds) Weight (Maximum) (No Pin Extensions) DVFL283R3S Min Continuous Transient, 1 sec Inhibited 1 Inhibited 2 No Load Full Load, to 10MHzINH1 Pin Open Circuit Voltage INH2 Pin Open Circuit Voltage UVLO Turn On UVLO Turn Off OUTPUT Voltage Power Current Ripple Voltage Line Regulation Load Regulation Voltage Trim EFFICIENCY Full Load, to 10MHz VIN 40V No Load to Full Load Full LoadLOAD FAULT POWER DISSIPATION CAPACITIVE LOAD SWITCHING FREQUENCY SYNC FREQUENCY RANGE ISOLATION MTBF = 5V Duty Cycle VDC AIF = 55�C 2.
