DVETR2800S Series HIGH RELIABILITY HYBRID DC-DC CONVERTERS WITH INTEGRAL EMI FILTER DESCRIPTION FEATURES The DVETR 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 DVETR series is a fault tolerant magnetic feedback circuit. Operating at a nominal fixed frequency of 500 kHz per stage, these regulated, isolated units utilize well-controlled undervoltage lockout circuitry to eliminate slow startup 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 40 Watts Output Power Fault Tolerant 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 Solder Seal Hermetic Package High Power Density: > 30 W/in3 Custom Versions Available Additional Environmental Screening Available No External EMI Filter Required Meets MIL-STD-461C and MIL-STD-461D EMC Requirements Protects Against Conducted Susceptibility Specified in MIL-STD-461C, SC01 and CS02 Flanged and Non-flanged Versions Available MIL-PRF-38534 Element Evaluated Components Figure 1 – DVETR2800S / DVETR2800SF DC-DC Converter (Not To Scale) 10031DSA 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 DVETR2800S 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) 1 Output Power Power Dissipation (Full Load, TCASE = +125°C) Parameter 50 VDC 80 Volts 40 Watts 14 Watts Conditions Junction Temperature Rise to Case Storage Temperature Lead Solder Temperature (10 seconds) Weight DVETR283R3S Min Typ +15°C -65°C to +150°C 270°C 50 grams DVETR2805S Max Min Typ Max Units STATIC Continuous 15 28 50 15 28 50 V Transient, 1 sec - - 80 - - 80 V Inhibited - - 6 - - 6 mA No Load - - 75 - - 75 mA 0 - 1.5 0 - 1.5 V Inhibit Pin Open Circuit Voltage 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 UVLO Turn Off4 11.0 - 14.5 11.0 - 14.5 V INPUT Voltage4 Current Inhibit Pin Input4 4 OUTPUT Voltage 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 - 20 0 - 30 W 0 - 6.06 0 - 6.0 A mVp-p Power3 Current3 VOUT Ripple Voltage VOUT Full Load, 20Hz to 20MHz - - 50 - - 50 Line Regulation VOUT VIN = 15V to 50V - - 20 - - 20 mV Load Regulation VOUT No Load to Full Load - - 50 - - 50 mV EFFICIENCY LOAD FAULT POWER DISSIPATION 65 - - 70 - - % Overload4 - - 12 - - 12 W Short Circuit - - 12 - - 12 W 4 CAPACITIVE LOAD SWITCHING FREQUENCY - - 1000 - - 1000 mF 350 475 550 350 475 550 kHz - 600 500 - 600 kHz SYNC FREQUENCY RANGE VH - VL = 5V, DC = 20-80% 500 ISOLATION 500 VDC 100 - - 100 - - MΩ THERMAL RESISTANCE Case to Ambient (qCA) - 19 - - 19 - °C/W MTBF (MIL-HDBK-217F) AIF @ TC = 55°C - 413 - - 413 - kHrs - - 400 - - 500 mVPK 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: VOUT Half Load to Full Load VIN = 16V to 40V VIN = 0V to 28V 1.
