DV200-2800D Series HIGH RELIABILITY DC-DC CONVERTERS DESCRIPTION FEATURES The DV200 series of high reliability, isolated DC-DC converters is operable over a wide (-55 °C to +100 °C) temperature range with no power derating. Unique to the DV200 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 and certified to MILPRF-38534 and MIL-STD-883. • • • • • • • • • • High Reliability Output Voltage Trim Up +10% or Down –20% Wide Input Voltage Range: 16 to 50 Volts Up to 200 Watts Output Power Up to 70% of Rated Output Power is Available for Each Output Radiation Immune Magnetic Feedback Circuit NO Use of Optoisolators Undervoltage Lockout Short Circuit Protection Current Limit Protection Input Transient Voltage: 55 Volts for 1 second 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 DVMN28 EMI Filter Figure 1 – DV200-2800D DC-DC Converter (Not To Scale) 15002DSB 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: [email protected] 1 DV200-2800D Series SPECIFICATIONS (TCASE = -55°C to +100°C, VIN = +28V ± 5%, Full Load, Unless Otherwise Specified) ABSOLUTE MAXIMUM RATINGS Input Voltage (Continuous) Input Voltage (Transient, 1 second) Output Power1,3 Power Dissipation (Full Load, TCASE = +100°C) Parameter 50 VDC 55 Volts 200 Watts 44 Watts Junction Temperature Rise to Case Storage Temperature Lead Solder Temperature (10 seconds) Weight (Maximum) DV200-2805D Conditions Min Typ +25°C -65°C to +135°C 270°C 115 grams DV200-2812D Max Min Typ Max Units STATIC Continuous INPUT 7 Voltage Current 16 28 50 16 28 50 V Transient, 1 sec - - 55 - - 55 V Inhibited - 6 10 - 6 10 mA No Load - 20 80 - 20 80 mA - - 100 - - 100 mAp-p 0 - 1.5 0 - 1.5 V 8 9.5 11 8 9.5 11 V 13.5 14 15.8 13.5 14 15.8 V V 5 Ripple Current Full Load , 20Hz to 10MHz Inhibit Pin Input 4 Inhibit Pin Open Circuit Voltage 4 UVLO Turn On 4 UVLO Turn Off OUTPUT Voltage 10 12 14 10 12 14 +VOUT TCASE = 25°C 4.95 5.00 5.05 11.88 12.00 12.12 V +VOUT TCASE = -55°C to +100°C 4.925 5.00 5.075 11.82 12.00 12.18 V -VOUT TCASE = 25°C 4.80 5.00 5.20 11.76 12.00 12.24 V -VOUT TCASE = -55°C to +100°C 4.85 5.00 5.25 11.52 12.00 12.48 V VIN = 18V to 50V - - 150 - - 175 W - - 90 - - 105 W - - 105 - - 122.5 W - - 63 - - 73.5 W - - 21 - - 10.2 A - - 12.6 - - 6.1 A ±VOUT VIN = 16V to 18V VIN = 18V to 50V Either Output VIN = 16V to 18V Either Output VIN = 18V to 50V Either Output VIN = 16V to 18V Either Output 5 Full Load , 20Hz to 10MHz - 50 150 - 50 200 mVp-p +VOUT VIN = 18V to 40V - 10 80 - 10 80 mV -VOUT VIN = 18V to 40V - 10 200 - 10 200 mV +VOUT No Load to Full Load 5 - 10 80 - 10 80 mV -VOUT No Load to Full Load 5 - 10 200 - 10 200 mV -VOUT V1+ Load 30% - Load 70% V2+ Load 70% - Load 30% - - 550 - - 550 mV Total 3,6,7 Power ±VOUT Current 3,6,7 ±VOUT Ripple Voltage Line Regulation Load Regulation Cross Regulation Voltage Trim Full Load EFFICIENCY -20 - 10 -20 - 10 % 5 79 82 - 80 84 - % 4 - - 80 - - 80 W Short Circuit - - 80 - - 80 W Either Output - - 1000 - - 1000 µF 450 500 550 450 500 550 kHz 450 - 550 450 - 550 kHz 100 - - 100 - - MΩ - 955 - - 955 - kHrs Full Load LOAD FAULT POWER DISSIPATION 4 CAPACITIVE LOAD Overload SWITCHING FREQUENCY ISOLATION VH – VL = 5V Duty Cycle = 20% - 80% 500 VDC, TCASE = 25°C MTBF (MIL-HDBK-217F) GB @ TC = 55°C SYNC FREQUENCY RANGE 15002DSB 2 DV200-2800D Series SPECIFICATIONS (TCASE = -55°C to +100°C, VIN = +28V ± 5%, Full Load, Unless Otherwise Specified) ABSOLUTE MAXIMUM RATINGS Input Voltage (Continuous) Input Voltage (Transient, 1 second) Output Power1,3 Power Dissipation (Full Load, TCASE = +100°C) Parameter 50 VDC 55 Volts 200 Watts 44 Watts Conditions Junction Temperature Rise to Case Storage Temperature Lead Solder Temperature (10 seconds) Weight (Maximum) DV200-2805D +25°C -65°C to +135°C 270°C 115 grams DV200-2812D Min Typ Max Min Typ Max - - 500 - - 600 Units DYNAMIC Load Step Output Transient ±VOUT 2 Load Step Recovery Line Step Output Transient 4 ±VOUT 2, 4 Line Step Recovery Turn On Delay Turn On Overshoot Notes: 1. 2. 3. 4. 5. 6. 7. ±VOUT Half Load to Full Load VIN = 18V to 40V VIN = 0V to 28V mVPK - - 500 - - 500 µSec - 300 600 - 600 1200 mVPK - 300 500 - 300 500 µSec - 20 30 - 20 30 mSec - - 50 - - 50 mVPK Dependant on output voltage.
