Product Description
The V048K120T025 V•I Chip Voltage Transformation
Module (VTM) breaks records for speed, density and
efficiency to meet the demands of advanced DSP, FPGA,
and ASIC at the point of load (POL) while providing
isolation from input to output. It achieves a response
time of less than 1 µs and delivers up to 25 A in a
volume of less than 0.25 in3 with unprecedented
efficiency. It may be paralleled to deliver hundreds of
amps at an output voltage settable from 6.5 to 13.7 Vdc.
The VTM V048K120T025’s nominal output voltage is
12 Vdc from a 48 Vdc input Factorized Bus, Vf, and is
controllable from 6.5 to 13.7 Vdc at no load, and from
6.5 to 13.4 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 = 1/4 , for applications requiring a programmable
output voltage at high current and high efficiency.
Closing the loop back to an input Pre-Regulation Module
(PRM) or DC-DC converter enables tight load regulation.
The 12 V VTM achieves break-through power density of
1200 W/in3 in a V•I Chip package compatible with
standard pick-and-place and surface mount assembly
processes. The V•I Chip BGA package supports in-board
mounting with a low profile of 0.16" (4 mm) over the
board.
A J-lead package option supports on-board surface
mounting with a profile of only 0.25" (6 mm) over the
board. 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.

Pin/Control Functions
PRELIMINARY
V•I Chip Voltage Transformation Module
+IN/-IN DC Voltage Ports
The VTM input should not exceed the high end of the range 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.
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
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 in order to restart the VTM.
Primary Auxiliary Supply – The PC port can source up to 2.4 mA
at 5 Vdc.
Figure 9—VTM BGA configuration
+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 19 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.
