Product Overview
The VI BRICK VTM Current Multiplier
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
VI BRICK 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
package occupying ~ 2 square inches.
The Military COTS VI BRICK VTMs are
optimized for use with the Military
Pre-Regulator Module to implement a
Factorized Power Architecture (FPA).
Together, the PRMTM + VTM set provides
the full functionality of a DC-DC converter,
but with breakthrough performance and
flexibility in a rugged, miniature package.
The companion VI BRICK PRM for the MT036
family of VI BRICK VTMs is the 28 Vdc input
MR028A036M012FP, 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.
By factorizing the DC-DC power conversion
into its essential elements – isolation and
transformation on the one hand, and the
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.
The VI BRICK 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.

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.

MT036 SERIES

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.

PIN / CONTROL FUNCTIONS
+In / -In DC Voltage Ports
The VTM input should not exceed the maximum specified. 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.
TM – For Factory Use Only
VC – VTM 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.
Figure 9 — VI BRICK VTM pin configuration (viewed from pin side)
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.

The Primary Control (PC) port is a multifunction port for controlling the
VTM as follows:
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.
+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. Limited-life
electrolytic capacitors required with conventional converters can be
reduced or even eliminated, saving cost and valuable board real estate.

APPLICATION NOTES & TEST CIRCUIT
Parallel Operation
In applications requiring higher current or redundancy, VTMs can be
operated in parallel without adding control circuitry or signal lines. To
maximize current sharing accuracy, it is imperative that the source and
load impedance on each VTM in a parallel array be equal. If VTMs are
being fed by an upstream PRM, the VC nodes of all VTMs must be
connected to the PRM VC.
To achieve matched impedances, dedicated power planes within the PC
board should be used for the output and output return paths to the
array of paralleled VTMs. This technique is preferable to using traces of
varying size and length.
The VTM power train and control architecture allow bi-directional power
transfer when the VTM is operating within its specified ranges. Bi-directional power processing improves transient response in the event of an
output load dump. The VTM may operate in reverse, returning output
power back to the input source. It does so efficiently.
Anomalies in the response of the source will appear at the output of the
VTM, multiplied by its K factor of 1/8 . The DC resistance of the source
should be kept as low as possible to minimize voltage deviations on the
input to the VTM. If the VTM is going to be operating close to the high
limit of its input range, make sure input voltage deviations will not
trigger the input overvoltage turn-off threshold.
Input Fuse Recommendations
VI BRICKs are not internally fused in order to provide flexibility in
configuring power systems. However, input line fusing of VI BRICKs must
always be incorporated within the power system. A fast acting fuse is
required to meet safety agency Conditions of Acceptability. The input
line fuse should be placed in series with the +In port. For agency
approvals and fusing conditions, click on the link below:
http://www.vicorpower.com/technical_library/technical_documentation/quality_
and_certification/safety_approvals/
Input Impedance Recommendations
To take full advantage of the VTM’s capabilities, the impedance of the
source (input source plus the PC board impedance) must be low over a
range from DC to 5 MHz. The input of the VTM (factorized bus) should
be locally bypassed with a 8 µF low Q aluminum electrolytic capacitor.
Additional input capacitance may be added to improve transient
performance or compensate for high source impedance. The VTM has
extremely wide bandwidth so the source response to transients is usually
the limiting factor in overall output response of the VTM.
