P R E L I M I N A RYThe VTM V048K015T80’s nominal output voltage is
1.5 Vdc from a 48 Vdc input factorized bus, Vf, and is
controllable from 1.0 to 1.8 Vdc at no load, and from
0.9 V to 1.7 V at full load, over a Vf input range of 32 to
57.6 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=1/32, and an output resistance, ROUT =1.3 milliohm,
to enable applications requiring a programmable low
output voltage at high current and high efficiency.

The 1.5V 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" (4mm) over the
board. A J-lead package option supports on-board
surface mounting with a profile of only 0.25" (6mm)
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
+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. An internal
over/under voltage lock-out function prevents operation outside
of the specified input range. The VTM will turn on when the
input voltage rises above the under voltage lock-out specified.
If the input voltage exceeds the over voltage lock-out, the VTM
will shutdown until the over voltage fault clears. 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.
A minimum 8 µF Aluminum Electrolytic capacitor should be
applied at the input of the VTM. Additional capacitance, e.g.
100 µF, may be added to enhance dynamic performance or to
compensate for high source impedance.

Figure 15—VTM BGA configuration
The Signal Ground (SG) pin provides a Kelvin return for the
Primary Control (PC) and Temperature Monitor (TM) ports.
Even though the SG pin is referenced to the –IN of the VTM, it
should not be used as an additional –IN connection.
P R E L I M I N A RYPC–PrimaryControl
The Primary Control (PC) pin is a multifunction pin for
controlling the VTM as follows:
Enable/Disable – If the PC is left floating or is pulled to
logic HI, the VTM output is enabled. To disable the output,
the PC pin must be pulled lower than 2.4 V, referenced to
SG. Optocouplers, open collector transistors or relays can
be used to control the PC pin. The PC port should not be
toggled at a rate higher than 1 Hz.

any of these abnormal conditions the PC port will toggle as
shown in Figure 14.
To take full advantage of the VTM, the user should note the
low output impedance of the device as shown in Figure 9.

(+27ºC) the TM output is 3.0 V and varies 10 mV/ºC. TM
accuracy is +/-5ºC if the SG pin is used as the ground return of
the TM signal. This feature is useful for validating the thermal
design of the system as well as monitoring the VTM
temperature in the final application.
