VPT100+2800S Series HIGH RELIABILITY COTS DC-DC CONVERTERS DESCRIPTION FEATURES The VPT100+ series of isolated COTS DC-DC converters is a cost effective solution for many demanding high reliability applications. A wide input voltage range accommodates nominal 28V inputs including avionics, mobile, ground systems, and other applications. A high efficiency design using synchronous rectification reduces input power requirements and eases thermal management. Low input and output ripple, fixed operating frequency, current sharing capability, and companion EMI filters simplify system design and compliance. A proven design heritage, no optoisolators and a rugged all metal package ensure long term reliability. * * * * * The VPT100 series is intended for harsh environments including severe vibration, shock and temperature cycling. Testing is to JESD22, MIL-STD810, and MIL-STD-883. These converters are designed and manufactured in the USA in a facility certified to ISO9001, J-STD-001 and IPC-A-610. * * * * * * * * * * * High Reliability at Low Cost Parallel Up to 5 Units With Current Sharing Up to 100 Watts Maximum Output Power High Efficiency, Up to 91% Wide Input Voltage Range: 16 to 40 Volts per MIL-STD-704 and MIL-STD-1275 High Input Transient Voltage: 50 Volts for 1 sec Input Undervoltage Lockout Fixed Frequency Output Voltage Trim (+10% / -20% ) Fast Startup time with Soft Start Current Limit Protection Short Circuit Protection Magnetic Feedback, no Optoisolators Wide Temperature Range, -55C to 100C Six Sided Metal Rugged Enclosure Meets MIL-STD-461C/D/E Conducted Emissions Requirements When Used With a VPTF series EMI Filter 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 Figure 1 - VPT100+2800S Converter (Not To Scale) DS90220B 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 VPT100+2800S Series SPECIFICATIONS (TCASE = -55C to +100C, 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 = +100C) Parameter 40 VDC 50 Volts 100 Watts 18 Watts Conditions Junction Temperature Rise to Case Storage Temperature Lead Solder Temperature (10 seconds) Weight (Maximum) VPT100+283R3S Min Typ +17C -55C to +125C 300C 76 Grams VPT100+2805S Max Min Typ Max Units STATIC Continuous INPUT 4 Voltage Current Ripple Current Inhibit Pin Input 16 28 40 16 28 40 V Transient, 1 sec - - 50 - - 50 V Inhibited - - 5 - - 5 mA No Load - 80 150 - 80 150 mA Full Load, 20Hz to 10MHz - - 180 - - 200 mAp-p 4 Inhibit Pin Open Circuit Voltage 4 UVLO Turn On 4 UVLO Turn Off OUTPUT Voltage 1.5 0 - 1.5 V 14.0 9.0 11.0 14.0 V 14.5 - 15.8 14.5 - 15.8 V V 14.0 - 15.0 14.0 - 15.0 TCASE = 25C 3.25 3.30 3.35 4.925 5.00 5.075 V VOUT TCASE = -55C to +100C 3.217 3.30 3.383 4.875 5.00 5.125 V 0 - 66 0 - 100 W 3 Current 11.0 VOUT Power 3 0 9.0 0 - 20 0 - 20 A Ripple Voltage VOUT VOUT Full Load, 20Hz to 10MHz - - 150 - - 150 mVp-p Line Regulation VOUT VIN = 16V to 40V - - 20 - - 20 mV VOUT No Load to Full Load mV Load Regulation Share Pin Voltage 4 4 Current Share Accuracy EFFICIENCY LOAD FAULT POWER DISSIPATION Overload 4 Short Circuit 4 CAPACITIVE LOAD SWITCHING FREQUENCY VH-VL=5V SYNC FREQUENCY RANGE Duty Cycle = 50% ISOLATION 500 VDC MTBF (MIL-HDBK-217F) GM @ TC = 55C - - 50 - - 50 0 - 5 0 - 5 V - 5 - - 5 - % 85 90 - 85 90 - % - - 24 - - 24 W - - 24 - - 24 W - - 1000 - - 1000 F 230 260 290 230 260 290 kHz 240 - 325 240 - 325 kHz 100 - - 100 - - M - 344 - - 344 - kHrs - - 250 - - 250 mVPK - - 300 - - 300 Sec - - 300 - - 300 mVPK - - 150 - - 150 Sec - 4 10 - 4 10 mSec - 0 15 - 0 25 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 Notes: VOUT Half Load to Full Load VIN = 16V to 40V VIN = 0V to 28V 1.
