DESCRIPTION The V• I Chip Voltage Transformer is a high efficiency (>91.5%) Sine Amplitude Converter (SAC)TM 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, which means that capacitance normally at the load can be located at the input to the Sine Amplitude Converter. Since the K factor of the VIV0007TFJ is 1/32, that capacitance value can be reduced by a factor of 1024, resulting in savings of board area, materials and total system cost. The VIV0007TFJ is provided in a V• I Chip package compatible with standard pick-and-place and surface mount assembly processes. The co-molded V•I Chip package provides enhanced thermal management due to large thermal interface area and superior thermal conductivity. With high conversion efficiency the VIV0007TFJ increases overall system efficiency and lowers operating costs compared to conventional approaches. The VIV0007TFJ enables the utilization of Factorized Power ArchitectureTM providing efficiency and size benefits by lowering conversion and distribution losses and promoting high density point of load conversion.

VIV0007TFJ
16.0 LAYOUT CONSIDERATIONS The VIV0007TFJ 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 VTM as possible. The layout must also prevent the high output current of the VIV0007TFJ 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) .
PRELIMINARY DATASHEET
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. Equalizing the current paths is most easily accomplished by centering the VTM 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 and 24.
