MIL-COTS MV036 SERIES VTMTM Transformer • Isolated 1-50 Vout • Low weight • High density • -55°C to 125°C operation • Small footprint • 1 µs transient response TM • ZVS / ZCS Sine Amplitude Converter • 4.5 million hours MTBF • 3 MHz effective switching frequency • Up to 96.5% efficiency © • Surface-mount package Absolute Maximum Ratings Product Description The VTM Transformer is a V•I Chip product that provides extremely fast, efficient, and quiet fixed ratio voltage division (or current multiplication). With twelve voltage division ratios from 1:1 to 1:32, the isolated VTM provides the user with the flexibility to supply up to 100 A or 120 W at any output voltage from 1 to 50 Vdc in a surface mount package occupying ~1 square inch. Parameter The Military VTMs are optimized for use with the Military PRMTM Regulator to implement a Factorized Power ArchitectureTM (FPATM). Together, the PRM + VTM chip set provides the full functionality of a DC-DC converter, but with breakthrough performance and flexibility in a rugged, miniature package. The companion PRM for the MV036 family of VTMs is the 28 Vdc input MP028F036M12AL, which operates from an input range of 16-50 Vdc (the data sheet is available at vicorpower.com). The VTM can also be used as a standalone POL product. TM By factorizing the DC-DC power conversion into its essential elements – the VTM’s isolation and transformation on the one hand, and the PRM’s output voltage control and regulation on the other – and arranging those functions in a sequence that maximizes system performance, FPA offers a fundamentally new and significantly improved approach to power conversion. +In to -In PC to -In VC to -In Unit Vdc 100 Vdc -0.3 to 7.0 Vdc Notes For 100 ms -0.3 to 19.0 Vdc Model specific Vdc Contact factory Isolation voltage 2,250 Vdc Input to Output Output current Model specific A See Table 1 1.5 • Iout A For 1 ms +Out to -Out Peak output current Output power 120 W Peak output power 180 W For 1 ms 225 °C MSL 5 245 °C MSL 6 Operating junction temperature [a] -55 to 125 °C M - Grade Storage temperature -65 to 125 °C M - Grade Case temperature Note: [a] The referenced junction is defined as the semiconductor having the highest temperature. This temperature is monitored by a shutdown comparator. Part Numbering Format The VTM’s fast dynamic response and low noise eliminate the need for bulk capacitance at the load, substantially increasing the POL density while improving reliability and decreasing cost. The low profile VTM (0.265 inches, 6,73 mm) is available with J-leads for surface mount or pins for through hole applications. vicorpower.com Values -1.0 to 60 800-735-6200 MV 036 Voltage Transformation Module Input Voltage Designator F 120 M Output Voltage Designator (=VOUT x10) Configuration F = J-lead T = Through hole V•I Chip Transformer 010 Output Current Designator (=IOUT) Product Grade Temperatures (°C) Grade Storage Operating (TJ) M -65 to125 -55 to125 MV036 SERIES Rev. 2.8 Page 1 of 10 Electrical Specifications Input Specs (Conditions are at 36 Vin, full load, and 25°C ambient unless otherwise specified) Parameter Input voltage range Min Typ Max Unit Note 26 36 50 Vdc Operable down to zero V with VC voltage applied 1 V/µs 55.5 57.5 Vdc 3.5 Adc 3.0 6.0 W Input dV/dt Input overvoltage turn-on 50.5 54.4 Input overvoltage turn-off Vdc Input current No load power dissipation 1.5 Continuous Low line to high line Output Specs (Conditions are at 36 Vin, full load, and 25°C ambient unless otherwise specified) Parameter Min Typ Output voltage K•VIN – IO•ROUT NOM Rated DC current 0 100 Peak repetitive current 150% DC current limit Current share accuracy Efficiency Load capacitance Output overvoltage setpoint Output ripple voltage (typ) No external bypass 10 µF bypass capacitor Effective switching frequency Line regulation Load regulation Transient response Response time Recovery time Max See Table 1 160% 5 10 Unit Note Vdc No load Vdc Adc Full load 26 - 50 VIN See Table 1 IMAX (A) Max pulse width 1ms, max duty cycle 10%, baseline power 50% INOM (A) Module will shut down when current limit is reached or exceeded % See Table 2, Page 3 See Table 2 when used with PRM 110% 50 2 2.5 0.99K ROUTMIN 3.0 K 200 1 vicorpower.com 800-735-6200 115% VOUT MAX 250 20 3.6 1.01K ROUTMAX mV mV MHz mΩ See Figures 2 and 5 See Figure 6 Model dependent VOUT = K•VIN at no load, See Table 1 See Table 1 ns µs See Figures 7 and 8 See Figures 7 and 8 V•I Chip Transformer MV036 SERIES Rev. 2.8 Page 2 of 10 Electrical Specifications (continued) Military Cots VTM Family Part Numbers and Ranges No Load Output Voltage (Vdc) Rout (mΩ) K-Factor Rated Output Current (A) @26 Vin @ 50 Vin Min Nom Max MV036F011M100 1/32 100 0.82 1.55 0.5 0.85 1.3 MV036F015M080 1/24 80 1.1 2.0 1.0 1.25 1.5 MV036F022M055 1/16 55 1.63 3.1 1.4 1.75 2.0 MV036F030M040 1/12 40 2.2 4.1 1.45 2.4 3.4 MV036F045M027 1/8 27 3.3 6.2 3.5 5.1 6.6 MV036F060M020 1/6 20 4.3 8.3 5.0 8.0 10 MV036F072M017* 1/5 16.6 6.4* 10 6.0 9.6 12 MV036F090M013 1/4 13.3 6.5 12.5 6.9 9.3 11.6 MV036F120M010 1/3 10.0 8.7 16.6 25 31 35 MV036F180M007 1/2 6.7 13 25 27.5 35.7 46.4 MV036F240M005 2/3 5.0 17.4 33 49.3 70.6 91.8 MV036F360M003 1 3.3 26 50 140 170 200 Part Number Table 1 — VTM part numbers * Low line input voltage 32 V Part Number Typical Full Load Efficiency at nom Vout (%) Typical Half Load Efficiency at nom Vout (%) Maximum Load Capacitance (µF) MV036F011M100 89.5 91.5 48128 MV036F015M080 92 94 27072 MV036F022M055 94 94.5 12032 MV036F030M040 94 95.0 6768 MV036F045M027 95.3 96.5 3008 MV036F060M020 95.3 96.8 1692 MV036F072M017 96.5 96.5 1175 MV036F090M013 96.3 95.5 752 MV036F120M010 95.5 95.5 423 MV036F180M007 96.0 95.2 188 MV036F240M005 95.0 94.8 106 MV036F360M003 96 96 47 Table 2 — Typical efficiency and maximum load capacitance, by part number Control Pin Functions VC – VTM Control PC – Primary Control The VC port is multiplexed. It receives the initial VCC voltage from an upstream PRM, synchronizing the output rise of the VTM with the output rise of the PRM. Additionally, the VC port provides feedback to the PRM to compensate for the VTM output resistance. In typical applications using VTMs powered from PRMs, the PRM’s VC port should be connected to the VTM VC port. The Primary Control (PC) port is a multifunction port for controlling the VTM as follows: In applications where a VTM is being used without a PRM, 14 V must be supplied to the VC port for as long as the input voltage is below 26 V and for 10 ms after the input voltage has reached or exceeded 26 V. The VTM is not designed for extended operation below 26 V. The VC port should only be used to provide VCC voltage to the VTM during startup. vicorpower.com 800-735-6200 Disable – If PC is left floating, the VTM output is enabled. To disable the output, the PC port must be pulled lower than 2.4 V, referenced to -In. Optocouplers, open collector transistors or relays can be used to control the PC port. Once disabled, 14 V must be re-applied to the VC port to restart the VTM. Primary Auxiliary Supply – The PC port can source up to 2.4 mA at 5 Vdc.

Be aware of this limit in applications where the VTM is being driven above its nominal output voltage. If less than 26 Vdc is present at the +In and -In ports, a continuous VC voltage must be applied for the VTM to process power. Otherwise VC voltage need only be applied for 10 ms after the voltage at the +In and -In ports has reached or exceeded 26 Vdc. If the input voltage exceeds the overvoltage turn-off, the VTM will shutdown. The VTM does not have internal input reverse polarity protection. Adding a properly sized diode in series with the positive input or a fused reverse-shunt diode will provide reverse polarity protection. 4 3 2 +Out B B C C D D +In E E -Out 1 A A F G H TM H J VC J K PC K +Out TM – For Factory Use Only -Out L L M M N N P P R R -In T T VC – VTM Control The VC port is multiplexed.

Primary Auxiliary Supply – The PC port can source up to 2.4 mA at 5 Vdc. +Out / -Out DC Voltage Output Ports The output and output return are through two sets of contact locations. The respective +Out and –Out groups must be connected in parallel with as low an interconnect resistance as possible. To take full advantage of the VTM, the user should note the low output impedance of the device. The low output impedance provides fast transient response without the need for bulk POL capacitance. Limitedlife electrolytic capacitors required with conventional converters can be reduced or even eliminated, saving cost and valuable board real estate. vicorpower.com 800-735-6200 V•I Chip Transformer MV036 SERIES Rev. 2.8 Page 6 of 10 Mechanical Drawings TOP VIEW ( COMPONENT SIDE) BOTTOM VIEW NOTES: mm 1.
