DVFL2800S Series HIGH RELIABILITY HYBRID DC-DC CONVERTERS DESCRIPTION FEATURES The DVFL 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 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 up to +10% or down –20%. • • • • 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 Parallel Up to 5 Units With Current Sharing Output Voltage Trim Up +10% or Down –20% Wide Input Voltage Range: 16 to 40 Volts per MIL-STD-704 Up to 120 Watts Output Power Radiation Immune Magnetic Feedback Circuit NO Use of Optoisolators Undervoltage Lockout 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 Figure 1 – DVFL2800S DC-DC Converter (Not To Scale) 12010DSB 17921 Bothell-Everett Highway, Suite 108 Bothell, WA 98012 http://www.vpt-inc.com Sales Information: Phone: (425) 487-4850 Fax: (425) 487-4802 E-mail: [email protected] 1 DVFL2800S Series SPECIFICATIONS (TCASE = -55°C to +125°C, VIN = +28V ± 5%, Full Load, Unless Otherwise Specified) ABSOLUTE MAXIMUM RATINGS Input Voltage (Continuous) Input Voltage (Transient, 1 second) Output Power1 Power Dissipation (Full Load, TCASE = +125°C) Parameter 40 VDC 50 Volts 120 Watts 41 Watts Conditions Junction Temperature Rise to Case Storage Temperature Lead Solder Temperature (10 seconds) Weight DVFL283R3S +15°C -65°C to +150°C 270°C 100 grams DVFL2805S Min Typ Max Min Typ Max 16 28 40 16 28 40 Units STATIC Continuous INPUT 4 Voltage V Transient, 1 sec - - 50 - - 50 V Inhibited 1 - - 3 - - 3 mA Current Inhibited 2 - - 70 - - 70 mA No Load - - 120 - - 120 mA Ripple Current Full Load, 20Hz to 10MHz - - 80 - - 80 mAp-p 0 - 1.5 0 - 1.5 V INH1 Pin Input 4 INH2 Pin Input 4 0 - 1.0 0 - 1.0 V INH1 Pin Open Circuit Voltage 4 10.5 - 13.5 10.5 - 13.5 V INH2 Pin Open Circuit Voltage 4 5.0 - 8.0 5.0 - 8.0 V UVLO Turn On 4 UVLO Turn Off OUTPUT Voltage 14.5 - 16.0 14.5 - 16.0 V 14.0 - 15.5 14.0 - 15.5 V VOUT TCASE = 25°C 3.267 3.30 3.333 4.95 5.00 5.05 V VOUT TCASE = -55°C to +125°C 3.25 3.30 3.35 4.925 5.00 5.075 V 0 - 66 0 - 100 W - - 20 - - 20 A - - 80 - - 80 mVp-p Power Current VOUT Ripple Voltage VOUT Full Load, 20Hz to 10MHz Line Regulation VOUT VIN = 16V to 40V - - 20 - - 20 mV Load Regulation VOUT No Load to Full Load - - 80 - - 100 mV VOUT Full Load -10 - 10 -20 - 10 % 2.0 - 3.0 2.0 - 3.0 V 68 - - 72 - - % - - 80 - - 80 W - - 80 - - 80 W - - 1000 - - 1000 µF Voltage Trim 4 Share Pin Voltage 4 EFFICIENCY LOAD FAULT POWER DISSIPATION Overload 4 Short Circuit 4 CAPACITIVE LOAD SWITCHING FREQUENCY 450 500 600 450 500 600 kHz VH – VL = 5V Duty Cycle = 20% - 80% 500 - 600 500 - 600 kHz ISOLATION 500 VDC 100 - - 100 - - MΩ THERMAL RESISTANCE Case to Ambient (θCA) - 12 - - 12 - °C/W MTBF (MIL-HDBK-217F) AIF @ TC = 55°C - 400 - - 400 - kHrs SYNC FREQUENCY RANGE Notes: 1.
