Product Description
The VTM Transformer is a V•I Chip
TM
product that
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 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
surface mount package occupying ~1 square inch.
The Military VTMs are optimized for use with the Military
PRM
TM
Regulator to implement a Factorized Power
Architecture
TM
(FPA
TM
). Together, the PRM + VTM chip set
provides the full functionality of a DC-DC converter, but
with breakthrough performance and flexibility in a
rugged, miniature package. The companion PRM for the
MV036 family of VTMs is the 28 Vdc input
MP028F036M12AL, 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 – the VTM’s isolation and
transformation on the one hand, and the PRM’s 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 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. The low profile VTM (0.265 inches,
6,73 mm) is available with J-leads for surface mount or
pins for through hole applications.

Control Pin Functions
VC – VTM Control
The VC port is multiplexed. It receives the initial V
CC
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 V
CC
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 to restart the VTM.
Primary Auxiliary Supply – The PC port can source up to 2.4 mA
at 5 Vdc.
