DV200-2800S 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. This product may incorporate one or more of the following U.S. patents: High Reliability Parallel Up to 5 Units With Current Sharing Output Voltage Trim Up +10% or Down –20% Wide Input Voltage Range: 16 to 50 Volts Up to 200 Watts Output Power 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 5,784,266 5,790,389 5,963,438 5,999,433 6,005,780 6,084,792 6,118,673 Figure 1 – DV200-2800S DC-DC Converter (Not To Scale) 15001DSF 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 DV200-2800S 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)4 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) DV200-283R3S +25°C -65°C to +135°C 270°C 115 Grams DV200-2805S Units Min Typ Max Min Typ Max 16 28 50 16 28 50 V - - 55 - - 55 V mA STATIC Continuous INPUT 5 Voltage Transient, 1 sec Current Ripple Current Inhibit Pin Input 4 Inhibit Pin Open Circuit Voltage 4 Inhibited - 6 10 - 6 10 No Load - 20 50 - 20 50 mA Full Load, 20Hz to 10MHz - - 100 - - 100 mAp-p To Disable Output 0 - 1.5 0 - 1.5 V 8 9.5 11 8 9.5 11 V 13.5 15 15.8 13.5 15 15.8 V V 4 UVLO Turn On 4 UVLO Turn Off OUTPUT Voltage 10.0 12.0 14.0 10.5 12.0 14.0 VOUT TCASE = 25°C 3.267 3.30 3.333 4.95 5.00 5.05 V VOUT TCASE = -55°C to +100°C 3.25 3.30 3.35 4.925 5.00 5.075 V VIN = 18V to 50V 0 - 100 0 - 150 W VIN = 16V to 18V 0 - 60 0 - 90 W VIN = 18V to 50V 0 - 30 0 - 30 A 3 Power Current 3 IOUT Ripple Voltage VIN = 16V to 18V 0 - 18 0 - 18 A VOUT Full Load, 10kHz to 10MHz - 50 150 - 50 150 mVp-p VOUT Full Load, 10kHz to 2MHz - 10 50 - 10 50 mVp-p Line Regulation VOUT VIN = 18V to 50V - 10 80 - 10 80 mV Load Regulation VOUT No Load to Full Load - 10 100 - 10 100 mV Voltage Trim VOUT Full Load -20 0 10 -20 - 10 % Full Load 74 80 - 79 83 - % - 45 - - 45 - W - 45 - - 45 - W - - 2000 - - 2000 µF EFFICIENCY LOAD FAULT POWER DISSIPATION Overload 4 Short Circuit 4 4 CAPACITIVE LOAD SWITCHING FREQUENCY 450 500 550 450 500 550 kHz SYNC FREQUENCY RANGE VH – VL = 5V Duty Cycle = 20% - 80% 450 500 550 450 500 550 kHz ISOLATION 500 VDC 100 - - 100 - - MΩ MTBF (MIL-HDBK-217F) GB @ TC = 55°C - 955 - - 955 - kHrs - 200 450 - 300 550 mVPK 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 VOUT Half Load to Full Load VIN = 18V to 40V VIN = 0V to 28V - 200 650 - 200 600 µSec - 150 300 - 150 300 mVPK - 50 150 - 50 150 µSec - 20 30 - 20 30 mSec - 0 30 - 0 50 mVPK Notes: 1.
