DESCRIPTION
The VI Chip® current multiplier is a high efficiency (>94%) Sine
Amplitude Converter™ (SAC™) operating from a 26 to 55 Vdc
primary bus to deliver an isolated output. The Sine Amplitude
Converter offers a low AC impedance beyond the bandwidth
of most downstream regulators; therefore capacitance normally
at the load can be located at the input to the Sine Amplitude
Converter. Since the K factor of the VTM48EF012T130A01 is
1/40, the capacitance value can be reduced by a factor of 1600,
resulting in savings of board area, materials and total system cost.
The VTM48EF012T130A01 is provided in a VI Chip® package
compatible with standard pick-and-place and surface mount
assembly processes. The co-molded VI Chip® package provides
enhanced thermal management due to a large thermal
interface area and superior thermal conductivity. The high
conversion efficiency of the VTM48EF012T130A01 increases
overall system efficiency and lowers operating costs compared
to conventional approaches.
The VTM48EF012T130A01 enables the utilization of Factorized
Power Architecture™ which provides efficiency and size
benefits by lowering conversion and distribution losses and
promoting high density point of load conversion.

15.0 FUSE SELECTION
In order to provide flexibility in configuring power systems
VI Chip® products are not internally fused. Input line fusing
of VI Chip® products is recommended at system level to provide
thermal protection in case of catastrophic failure.
The fuse shall be selected by closely matching system
requirements with the following characteristics:
• Current rating (usually greater than maximum current
of VTM module)
• Maximum voltage rating (usually greater than the maximum
possible input voltage)
• Ambient temperature
• Nominal melting I2t

D: VIN > VOUT /K, powertrain starts in normal mode
E: VIN supply ramps down
F: VIN > VOUT /K, powertrain transfers reverse energy
G: VOUT ramps down, VIN follows

VTM48EF012T130A01
17.0 LAYOUT CONSIDERATIONS
The VTM48EF012T130A01 requires equal current density along
the output J-leads to achieve rated efficiency and output power
level. The negative output J-leads are not connected internally
and must be connected on the board as close to the VTMT™
current multiplier as possible. The layout must also prevent the
high output current of the VTM48EF012T130A01 from
interfering with the input-referenced signals.
To achieve these requirements, the following layout guidelines
are recommended:
• The total current path length from any point on the V+OUT
J-leads to the corresponding point on the V-OUT J-leads should
be equal (see Figure 22) .
Figure 22 — Equal current path
• Use vias along the negative output J-leads to connect the
negative output to a common power plane.
• Use sufficient copper weight and number of layers to carry
the output current to the load or to the output connectors.
• Be sure to include enough vias along both the positive and
negative J leads to distribute the current among the layers
of the PCB.
• Do not run input-referenced signal traces (VC, PC, TM
and IM) between the layers of the secondary outputs.
• Run the input-referenced signal traces (VC, PC, TM and IM)
such that V-IN shields the signals. See AN:005 FPA Printed
Circuit Board Layout Guidelines for more details.
Figure 23 — Symmetric layout
Equalizing the current paths is most easily accomplished by
centering the VTM module output J-leads between the output
connections of the PCB and by designing the board such that
the layout is symmetric from both sides of the output and from
the front and back ends of the output as shown in Figures 23
