DVETR2800S Series HIGH RELIABILITY HYBRID DC-DC CONVERTERS WITH INTEGRAL EMI FILTER DESCRIPTION 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 and certified to MILPRF-38534 and MIL-STD-883. This product may incorporate one or more of the following U.S. patents: 5,784,266 5,790,389 5,963,438 5,999,433 6,005,780 6,084,792 6,118,673 FEATURES * * * * * * * * * * * * * * * * * * * * 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 Indefinite Short Circuit Protection Current Limit Protection Industry Standard Pinout High Input Transient Voltage: 80 Volts for 1 sec per MIL-STD-704A Precision 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, CS01 and CS02 Flanged and Non-flanged Versions Available MIL-PRF-38534 Element Evaluated Components Figure 1 - DVETR2800S / DVETR2800SF DC-DC Converter (Not To Scale) 1X031DSF 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: vptsales@vpt-inc.com 1 DVETR2800S Series SPECIFICATIONS (TCASE = -55C to +125C, 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 = +125C) 50 VDC 80 Volts 40 Watts 14 Watts Junction Temperature Rise to Case Storage Temperature Lead Solder Temperature (10 seconds) Weight (Maximum) (Un-Flanged / Flanged) DVETR283R3S Min 15 0 4 +15C -65C to +150C 270C (51 / 55) Grams Parameter STATIC INPUT 4 Voltage Current Inhibit Pin Input UVLO Turn On UVLO Turn Off OUTPUT Voltage Power 3 3 4 4 Conditions DVETR2805S Max 50 80 6 90 1.5 13.0 14.8 14.5 Typ 28 11.0 3.30 3.30 475 413 Min 15 0 9.0 12.0 11.0 4.95 4.90 0 0 70 450 100 - Typ 28 11.0 5.00 5.00 500 413 Max 50 80 6 90 1.5 13.0 14.8 14.5 5.05 5.10 30 6.0 50 20 50 16 16 1000 550 - Units Continuous Transient, 1 sec Inhibited No Load V V mA mA V V V V V V W A mVp-p mV mV % W W F kHz M kHrs Inhibit Pin Open Circuit Voltage 9.0 12.0 11.0 VOUT VOUT VOUT VOUT VOUT VOUT TCASE = 25C TCASE = -55C to +125C 3.267 3.25 0 0 3.333 3.35 20 6.06 50 20 50 16 16 1000 550 - Current Ripple Voltage Line Regulation Load Regulation EFFICIENCY Full Load, 20Hz to 10MHz VIN = 15V to 50V No Load to Full Load Overload 4 65 400 LOAD FAULT POWER DISSIPATION CAPACITIVE LOAD ISOLATION MTBF (MIL-HDBK-217F) 4 Short Circuit SWITCHING FREQUENCY 500 VDC AIF @ TC = 55C VOUT VOUT VOUT 100 - DYNAMIC Load Step Output Transient Load Step Recovery Line Step Recovery Turn On Delay Turn On Overshoot 2 4 Half Load to Full Load VIN = 16V to 40V VIN = 0V to 28V - 150 100 - 400 500 600 500 20 30 - 150 100 - 500 500 600 500 20 50 mVPK Sec mVPK Sec mSec mVPK Line Step Output Transient 2, 4 Notes: 1.
