DVSA2800D Series HIGH RELIABILITY HYBRID DC-DC CONVERTERS DESCRIPTION FEATURES The DVSA 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 DVSA series is a magnetic feedback circuit that is radiation immune. Operating at a nominal fixed frequency of 450 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 6 Watts Output Power 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 Projection Welded Hermetic Package High Power Density: > 19 W/in3 Custom Versions Available Additional Environmental Screening Available Meets MIL-STD-461C and MIL-STD-461D EMC Requirements When Used With a DVMA28 EMI Filter MIL-PRF-38534 Element Evaluated Components Figure 1 – DVSA2800D DC-DC Converter (Not To Scale) 12002DSA 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 DVSA2800D Series SPECIFICATIONS (TCASE = -55°C to +125°C, VIN = +28V ± 5%, Full Load5, Unless Otherwise Specified) ABSOLUTE MAXIMUM RATINGS Input Voltage (Continuous) Input Voltage (Transient, 1 second) 1 Output Power Power Dissipation (Full Load, TCASE = +125°C) Parameter 50 VDC 80 Volts 6 Watts 2.5 Watts Junction Temperature Rise to Case Storage Temperature Lead Solder Temperature (10 seconds) Weight DVSA2805D Conditions Min Typ +10°C -65°C to +150°C 270°C 15 grams DVSA2812D Max Min Typ Max Units STATIC Continuous INPUT Voltage4 Current Ripple Current 15 28 50 15 28 50 V Transient, 1 sec - - 80 - - 80 V Inhibited - - 6 - - 6 mA No Load - 30 60 - 30 60 mA Full Load5, 20Hz to 20MHz - 30 50 - 30 50 mAp-p 4 0 - 1.5 0 - 1.5 V Inhibit Pin Open Circuit Voltage4 9.0 11.0 13.0 9.0 11.0 13.0 V UVLO Turn On 13.0 - 14.8 13.0 - 14.8 V Inhibit Pin Input UVLO Turn Off 4 OUTPUT Voltage5 Power3,6 Current 3,6 Ripple Voltage Line Regulation Load Regulation Cross Regulation 11.0 - 14.5 11.0 - 14.5 V +VOUT TCASE = 25°C 4.95 5.0 5.05 11.88 12.0 12.12 V +VOUT TCASE = -55°C to +125°C 4.925 5.0 5.075 11.82 12.0 12.18 V -VOUT TCASE = 25°C 4.925 5.0 5.075 11.82 12.0 12.18 V -VOUT TCASE = -55°C to +125°C 4.90 5.0 5.10 11.76 12.0 12.24 V 0 - 5 0 - 6 W - 3.5 0 - 4.2 W Total ±VOUT Either Output 0 ±VOUT Either Output 0 - 0.7 0 - 0.35 A ±VOUT Full Load5, 20Hz to 20MHz - - 50 - - 50 mVp-p +VOUT VIN = 16V to 40V - 10 20 - 10 20 mV -VOUT VIN = 16V to 40V - 50 200 - 50 200 mV +VOUT No Load to Full Load5 - 10 50 - 10 50 mV -VOUT 5 No Load to Full Load - 50 200 - 50 200 mV -VOUT +Load 70%, -Load 30% +Load 30%, -Load 70% - - 450 - - 450 mV Full Load5 66 72 - 72 77 - % Overload4 - - 3 - - 3 W Short Circuit - - 3 - - 3 W Either Output - - 500 - - 500 mF 350 450 500 350 450 500 kHz EFFICIENCY LOAD FAULT POWER DISSIPATION CAPACITIVE LOAD4 SWITCHING FREQUENCY ISOLATION 500 VDC, TCASE = 25°C 100 - - 100 - - MΩ THERMAL RESISTANCE Case to Ambient (qCA) - 28 - - 28 - °C/W MTBF (MIL-HDBK-217F) AIF @ TC = 55°C - 457 - - 457 - kHrs See notes next page. 12002DSA 2 DVSA2800D Series SPECIFICATIONS (TCASE = -55°C to +125°C, VIN = +28V ± 5%, Full Load5, Unless Otherwise Specified) ABSOLUTE MAXIMUM RATINGS Input Voltage (Continuous) Input Voltage (Transient, 1 second) 1 Output Power Power Dissipation (Full Load, TCASE = +125°C) Parameter 50 VDC 80 Volts 6 Watts 2.5 Watts Conditions Junction Temperature Rise to Case Storage Temperature Lead Solder Temperature (10 seconds) Weight DVSA2805D +10°C -65°C to +150°C 270°C 15 grams DVSA2812D Min Typ Max Min Typ Max - - 300 - - 300 Units DYNAMIC Load Step Output Transient ±VOUT 2 Load Step Recovery Line Step Output Transient4 ±VOUT Line Step Recovery2, 4 Turn On Delay Turn On Overshoot2 Notes: 1. 2. 3. 4. 5. 6. ±VOUT Half Load to Full Load VIN = 16V to 40V VIN = 0V to 28V mVPK - - 400 - - 450 mSec - 500 1000 - 600 1200 mVPK - 300 500 - 300 500 mSec - 10 20 - 10 20 mSec - - 25 - - 50 mVPK Dependant on output voltage.
