The V048F080T030 V•I Chip Voltage Transformation
Module excels at speed, density and efficiency to meet
the demands of advanced power applications while
providing isolation from input to output. It achieves a
response time of less than 1 µs and delivers up to 30 A in
a volume of less than 0.295 in3 with unprecedented
efficiency. It may be paralleled to deliver higher power
levels at an output voltage settable from 4.34 to 9.16 Vdc.

The VTM V048F080T030’s nominal output voltage is 8
Vdc from a 48 Vdc input Factorized Bus, Vf, and is
controllable from 4.34 to 9.16 Vdc at no load, and from
4.04 to 8.89 Vdc at full load, over a Vf input range of 26
to 55 Vdc. It can be operated either open- or closed-loop
depending on the output regulation needs of the
application. Operating open-loop, the output voltage
tracks its Vf input voltage with a transformation ratio,
K = 1/6, for applications requiring an isolated output
voltage with high efficiency. Closing the loop back to an
input PRMTM regulator or DC-DC converter enables tight
load regulation.

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.

Bottom View
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.

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.

PC – Primary Control
Figure 9 — VTM pin configuration
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. Within the
specified input voltage range, the Level 1 DC behavioral model shown
in Figure 16 defines the output voltage of the VTM. The current source
capability of the VTM is shown in the specification table.
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 Note
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.
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.
Anomalies in the response of the source will appear at the output of
the VTM, multiplied by its K factor of 1/6. 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.
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.
Input Fuse Recommendations
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.
V•I Chips are not internally fused in order to provide flexibility in
configuring power systems. However, input line fusing of V•I Chips
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.
Input Impedance Recommendations
Application Notes
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
