P R E L I M I N A RYThe VTM V048K020T080’s nominal output voltage is
2 Vdc from a 48 Vdc input factorized bus, Vf, and is
controllable from 1.1 to 2.3 Vdc at no load, and from
1.1 to 2.2 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 = 1/24, and an output resistance, ROUT = 1.3 milliohm, to
enable applications requiring a programmable low
output voltage at high current and high efficiency.

Part Numbering
The 2 V VTM achieves break-through current density of
320 A/in3 in a VI Chip package compatible with
standard pick-and-place and surface mount assembly
processes. The VI 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
+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. A 14 V source
must be applied to the VC pin and voltage must be present at
the +In and -In ports in order for the VTM to process power. If
the input voltage exceeds the over voltage lock-out, 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.
VC – VTM Control
The VC port is multiplexed. It receives the initial Vcc voltage
from an upstream PRM, synchronizing the output rise of the

In applications where a VTM is being used without a PRM,
14 V must be supplied to the VC port for approximately 10 ms in
order for the VTM to startup. The VTM can be operated at
P R E L I M I N A RYinput voltages below 26 V as long as the VC voltage is applied.
PC – Primary Control
The Primary Control (PC) pin is a multifunction pin for
controlling the VTM as follows:
Disable – If the PC is left floating, the VTM output
is enabled. To disable the output, the PC pin must be pulled
lower than 2.4 V, referenced to -In. Optocouplers, open
collector transistors or relays can be used to control the PC

The output (+OUT) and output return (-OUT) are through two
pin. Once disabled, 14 V must be re-applied to the VC pin
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
TM – Temperature Monitor
source capability of the VTM is shown in the specification table.
The Temperature Monitor (TM) provides a linear output
proportional to the internal temperature of the VTM. At 300ºK
(+27ºC) the TM output is 3.0 V referenced to -In and varies
10 mV/ºC. TM accuracy is +/-5ºC. This feature is useful for
validating the thermal design of the system as well as
monitoring the VTM temperature in the final application.
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.
